Finding damping of composite  material by using ansys

any one please help me in finding damping of any composite material by using ansys  software and what analysis has to be done regarding that one.generally in ansys damping can be given as input but to get damping as the output of composite material how it can be done what model i has to use?

Hi all,

I have taken up this research project/attachment on
"characterising the fracture toughness of epoxy using mechanical
fatigue", and encountered lot's of problems while researching. I'm just
a student, not even in university, but rather still schooling (grade
10), so am completely new to this field, which explains my problem in
understanding all the lit reviews, lecture slides i found online.
Luckily, i found out this site, and would hope that someone can guide
me in the right direction!

James Robert Rice (JRR) was born on 3 December 1940 in Frederick, Maryland to Donald Blessing Rice and Mary Celia (Santangelo) Rice. Located some 50 miles northwest of the nation’s capital, Frederick was then a small city of about 20,000 people, set in a rural, farming area. Commemorated in Whittier’s poem about Dame Barbara Fritchie’s patriotism, Frederick was a crossroads for troop movements during the Civil War (1861-1865) and the birthplace of Francis Scott Key who wrote the American National Anthem. JRR’s mother Mary was the child of a Sicilian immigrant family and now resides in Adamstown, Maryland. The family of JRR’s father, Donald, had long lived in that part of the USA. Donald, who died in 1987, operated a gasoline station, served 3 terms as alderman and a term as mayor of Frederick City in the early 1950s, later founded a successful tire company, and, like Mary, was highly active in Frederick community affairs.

JRR was raised in Frederick, and was the second of three children. His older brother, Donald Blessing Rice Jr., served as corporate CEO of several companies (such as the RAND Corporation) in the private sector and one term as Secretary of the U.S. Air Force under the Bush Administration. He now resides in Los Angeles. JRR’s younger brother, Kenneth Walter Rice, continues to live in Frederick and runs the business started by his father.

JRR attended primary and secondary school at St. John's Literary Institute, a local parish school in Frederick. He played baseball and basketball, worked part‑time delivering newspapers and in his father's businesses, and read a lot. Influenced by his high school teachers of math and physics, recruited from Fort Dieterich, a local army base, JRR’s early interest in auto mechanics gradually evolved into an interest in mechanical engineering. Armed with several scholarships, he began undergraduate studies in that subject at Lehigh University in Bethlehem, PA, in 1958, one year after the launch of Sputnik propelled the U.S. into a keen competition in outer space with the then-USSR.

During his undergraduate studies at Lehigh, JRR realized his particular interest was in theoretical mechanics, especially fluid and solid mechanics, and applied mathematics. Under the influence of inspiring teachers including Ferdinand Beer, Fazil Erdogan, Paul Paris, Jerzy Owczarek, George Sih, and Gerry Smith, he did his subsequent studies in the engineering mechanics and applied mechanics programs. Paul Paris has said that for the courses JRR took from him, half of Paul’s preparation for each lecture consisted of answering the questions JRR had posed during the previous class meeting. Because of his proficiency in math and physics, JRR earned all his academic degrees, from B.S. to Ph.D in only six years (1958-1964), the shortest time in Lehigh’s record. Ferdinand Beer directed JRR’s M.S. and Ph.D. theses on stochastic processes, specifically on the statistics of highly correlated noise. The results were summarized in 1964 in his Ph.D. thesis, entitled “Theoretical Prediction of Some Statistical Characteristics of Random Loadings Relevant to Fatigue and Fracture”. At the same time, he continued working with George Sih on the subject of his undergraduate research project, elastic stress analysis of cracks along a bi-material interface. He independently developed a simple elastic‑plastic crack model, which turned out to be the same as D. S. Dugdale had already published, and then extended the model to the case of cyclic loads. His work on “The Mechanics of Crack Tip Deformation and Extension by Fatigue” was published in ASTM STP 415 in 1967, and was awarded the ASTM Charles B. Dudley Medal in 1969.

Professor Yonggang Huang from Northwestern University presented this
year's Nowinski Lecture at the University of Delaware on 12/5/2008, http://www.udel.edu/udaily/2009/nov/nowinskilecture112108.html.

The Nowinski Lecture Series honors Jerzy L. Nowinski, Professor Emeritus in Mechanical Engineering, for his contributions to the field of Applied Mechanics. Each year, one outstanding individual in Applied Mechanics is invited to present a lecture in the series. Below is the list of Nowinski speakers since the inception of the series, http://www.me.udel.edu/News_Events/Past_Events/nowinski_lecture.html . 

The Academy of Sciences of Turin has awarded James R. Rice, of Harvard University, the 2008 Panetti-Ferrari International Prize for Applied Mechanics.  The Academy was established in 1758 by Joseph Louis Lagrange, the Italian-born mathematician and astronomer known for his achievements in mechanics, calculus, and number theory. The prize is supported by successive endowments from the late Professors Modesto Panetti and Carlo Ferrari, 20th century leaders in Italian mechanics and aeronautics. First awarded as the Panetti Prize to Geoffrey I. Taylor of Cambridge UK in 1958, an award is made every 2-3 years and currently includes a €15,000 premium.

Presented at the reception in honor of Professor John W. Hutchinson.  I should explain the context of my remarks. In 1995, Bob McMeeking, having exhausted himself in the endeavor of forming a useful intellect from so little to work with, appealed to a higher power and sent me to Cambridge. The week of my arrival, Prof. Hutchinson surveyed the challenge before him, and responded with the temperate and sage wisdom we have all come to admire: he packed his bags and moved to Denmark....For a whole year.... This action inspired many in mechanics. McMeeking left the country the same year (apparently to recuperate from our time together). Evans apparently entered into negotiations withe the rest of the Ivy League. And John Bassani, unwittingly left holding the bag while on sabbatical at Harvard, enforced a strict policy of my only talking to him on the way to weekly basketball games.

Delivered at the Annual Dinner of the Applied Mechanics Division, in the Back Bay Ballroom, Sheraton Hotel, Boston, in the evening of 4 November 2008, the Election Day of the United States of America 

Before I start, let me mention my wife, Eva's contribution to this lecture. She said to me to make a draft first and then she would be happy to help me to tighten it up later on. After a day and half's work, I took the result to her who quickly informed me that: it was much too long, contained too much unnecessary details, and that, it can be reduced by 3/4th without losing anything significant!

After another several hours of effort, I took the product to her who immediately requested further reduction, by at least a factor of two!

This process went on for a few cycles when, finally, she said: "if you cut it in half, then it might be OK."

I did.

She looked at it and asked me to read it out loud.

I read: "Ladies and gentlemen, and the Timoshenko Medal Committee, thank you very much."

"Now, that is a good after dinner speech", she shouted.

Then she thought for a minute and said: "You Persians are very wordy.
If you leave out the ‘very much', and just say ‘thank you' then it
would be a great after dinner speech!" 

A Mechanics-Guided Journey through Engineering Science

I wish to first thank our gracious MC, Professor Dan Inman, for his generous introduction.  I would also like to thank you, ladies and gentlemen, for being here tonight, after several arduous political weeks of having repeatedly heard from Joe the Established Politician, Joe the Unlicensed Plumber, and Jack the Unknown Electrician, just to mention a few, to hear from Sia, the also Unlicensed Mechanician.  

I am indeed, thrilled and honored to have been chosen as the 2008 Timoshenko Medalist, and wish to thank the Timoshenko Medal Committee for, at least from my point of view, a pretty good choice!
