Soil in ansys workbench

Submitted by Mina.M on

Hi everybody,

how can I define soil parameters just as cohesion and plasticity stress and strain of soil in "ansys workbench"?

I knew there is "drucker prager" model option in "ansys classic" to define these parameters but I couldn't find any option in "ansys workbench.

 

modeling a composite tube using ansys

Submitted by wissam hijazi on

hi everybody,

i am working with ansys and trying to madel  a composite tube i have chosen element "solid 46" the first problem i faced is in the "material model" "orthotropic material" i am working with 2d composite materials (plane stress) (i have Ex Ey Gxy)

in ansys for an orthotropic material we need to fill also Ez Gxz Gzy wich we dont have in plane stress .

also what system of coordinates should i use cartesian or cylindrical.

and for the mesh is it importsnt the kind of mesh or i can choose betwwn free and mapped.

Introduction to Cohesive Zone and Modelling DCB Test using Cohesive Elements

Submitted by craime on

I am currently working on a project to model DCB test in ABAQUS. My current problem lies in understanding cohesive zone modelling. I was wondering if anyone can forward me a couple of  materials regarding the introduction of cohesive zones?

 This would help me understand the material greatly and help me in modelling the DCB test.

 Another question in ABAQUS:  how do you implement the material properties for cohesive elements? in particular, what values should i be using for them? e.g. E, G1, G2?

Ferromagnetic, Piezoelectric & Magnetoelastic Plates & Shells Vibartions

Submitted by Alexander on

We are solved analytically and numerically by exact space treatment, proposed for elastic plates by Novatsky, the problems of determination of free vibrations of thin piezoelectric plates and shells frequences and mode comparision with Kirchoff theory, showing that in contrast to pure elastic case, the tables of frequences obtained by space treatment and by hypothesis are quite different. During last eight years you obtained the some results for magnetoelastic and ferromagnetic thin plates and shells, almost for all cases it is shown that Kirchoff hypothesis is not applicable.

An Introduction Course on Mechanics

Submitted by Ji Wang on

 

We are currently offerring an introductory course on mechanics for junior students for all fields and subjects.  It is a so called general knowledge course for students to know more on certain subjects and fields before a decision on choice of a major is made.  Since the Mechanics Department in our University has not been popular for so long, we have decided to evangalize our field with more glorious history of Mechanics: Newton, Bernoulli, Euler, Clausius, Faraday, and Einstein.

Symposium Honoring Professor J. W. Hutchinson at IMECE'08 (Boston)

Submitted by Mark E. Walter on

To coincide with this year’s IMECE in Boston, the Fracture and Failure Mechanics Technical Committee is organizing a series of sessions to honor Professor John W. Hutchinson’s seminal contributions as he moves into semi-retirement. The organizers request abstracts in contemporary research related to fracture and failure mechanics. Topics that relate to Professor Hutchinson's many past and present research activities in other areas are also welcome.

What is the difference between RVE and Unit Cell ?

Submitted by sspadhee on

I have been working in composites for sometime now. In the literature I have found that the words  "Representative Volume Element" (RVE) and "Unit Cell" (UC)  are  used frequently.  Some  authors treat them differently and some treat them  same. I am little bit confused can anyone PLEASE clarify the situation or suggest some good papers to read.

 

Thanks In Advance.
