I WANT TO find the flexural strength of laminated composites after it is subjected to cyclic loading
i have to use the output of the cyclic loading as the input to find the strength
i want to know the procedure for that
please help me out
In engineering sciences, we usually end up using either the second- or the fourth-order differential equations, and the MWR (the method of weighted residuals) works pretty well for them.
The question is: how about the first- and the third-order differential equations? Why don't we see any applications of MWR for these odd-ordered differential equations? What gives?
I have created a channel beam using 3D shell elements. It is subjected to two point loading each at 1/3rd length. I have performed STATIC RIKS analysis. Is it possible to draw bending moment diagram for this model? Orelse if i use section moments how can i interpret the maximum moment?
Your reply is highly appreciable.
I have carried out eigen buckling analysis of cylindrical shell under axial compression under unit load using abaqus in model-1 and in model -2 i carried out riks analysis gave imperfection 0.2mm fotr shell thickness 2mm radius 0.25m,h=0.5 m after the 100 increment the the shell is subjected to load which is obtained from first buckling load in first mode here how to get the collapse load
hi im prasath now im a CAE trainee. i want to know more about CAE analysis what are the necessary things i've to learn and experienced in this field?...
I want to try abaqus ductile damage model to simulate steel
failure in Abaqus. I read the manual, and have some ambiguities regarding its parameters.
Is there somebody to have experiences in ductile damage to share?
Good International news on Caltech and engineering. Ares Rosakis, chair of the Division of Engineering and Applied Science,describes Caltech as “a unique species among universities…a very interesting phenomenon”.More can be found in the attachment or at the link below
I've been trying to simulate flow conditions at 100 km altitude over a re entry capsule in fluent.
Density = 0.000000577 Kg/m3
I have updated my notes on the Griffith paper. I added more description on the experimental determination of surface tension of solids. Griiffith himself determined the surface tension of glass by an experimental setup. Udin et al (1949) described a setup based on the same principle. This setup is now known as the zero creep experiment.

The class started today. I'll be teaching fracture mechanics this semester. I'll be mostly using the class notes I wrote in 2010, but will post updated ones.
In today's class I covered "Trouble with linear elastic theory of strength." I have just posted updated notes of the lecture. The new notes begin with the follwoing paragraphs.
I recently posted a free, online, and
condensed version of my book Intermediate Mechanics of Materials, Second
Edition. It is posted on my website madhuvable.org
and can be used for reference or by self-learners. In addition to the
online book, there is a glossary of mechanics terms, brief reviews of
Statics, Matrix Algebra, Numerical Methods, and Mechanics of Materials.
This complements my earlier free-online book Introduction to Mechanics of Materials posted on this link .
Apples and oranges. Each element in a set is a pile containing some number of apples and some number of oranges. Adding two piles means putting them together, resulting in a pile in the set. Multiplying a pile and a real number r means finding in the set a pile r times the amount. We model each pile as a vector, and the set as a two-dimensional vector space over the field of real numbers.
A vector represents different objects as a single entity. A pile containing some number of apples and some number of oranges is a vector. The addition of two vectors does not require us to add apples and oranges. Rather, in adding two piles, we add apples to apples, and oranges to oranges. The addition of vectors generalizes the addition of numbers: adding two vectors corresponds to adding two lists of numbers in parallel.

Title of the course: New insights in Sports and Building Aerodynamics
This is an introductory post to a discussion on the advantages of multicellular organisms over single-celled eukaryotes from an energy harvesting viewpoint. It is intended for the New Mexico Tech biomechanics class but others can play.
As engineers we should seek for a numerical measure (or some measures) that allows us to decide how close an organism is to the optimum. Consider two cases: a seaweed in comparison to a single-cell photosynthetic eukaryote and a herbivore in comparison to a single-celled eukaryotic animal.
Comment on the possible answers, problems with the answers you previously gave or improve on the question. You will be graded on the quality of your comments over the next two weeks.
This afternoon, I had an extremely pleasant Google hangout with Daniel Suo, and Professors Zhigang Suo and Teng Li . Our main focus was on brainstorming ideas on how to improve the user experience on iMechanica. After an hour or so our conversation drifted towards educational topics including novel ways of incorporating technology in STEM education.
can i include mechanisms while creating DMIG in FEA?
I read with interest an excellent discussion about Linear Algebra in Mechanics. I am attaching Chapter I: Tensor Preliminaries from my book Elastoplasticity Theory, which includes Hill's analysis of induced tensors mentioned in the discussion.
How to consider a pretwisted tapered propeller balde either as beam orplate
When I was updating my very brief notes on tensors, it occurred to me to post on iMechanica a request for recommendation of textbooks on linear algebra. I was delighted to see Arash respond. I then asked for his opinion about the definition of tensor. He responded again, and we seemed to agree. Then Amit joined the discussion, and then others. That thread has become very interesting and very long.
But I have another issue with the way we use linear algebra. I wish to get your opinion. The issue is about scalars.
I'm working on a project & I'm in a trouble. I need to know creep relations for a porous material under undrained condition and constant stress. I'll be gratefull if you help me.
I attach some class notes developed by the late Professor Donald Carlson from which many generations of students at the University of Illinois learnt Continuum Mechanics.
Linear algebra is significant to many aspects of mechanics. For some years I have been using the book by Shilov. But this book may or may not be a good one to recommend to a student, depending on his or her prior experience. On StackExchange Mathematics, there are several excellent threads discussing textbooks of linear algebra. A particular recommendation was made for textbooks of linear algebra at three levels. Do you have any recommendations?
