A course on Advanced Elasticity, with emphasis on thermodynamics and soft active materials

Submitted by Zhigang Suo on

In the field of Solid Mechanics, Harvard has a sequence of 5 graduate courses:

The first course goes over linear elasticity, finite element method, vibration, waves, viscoelasticity, as well as some ideas of finite deformation.

My name is Bash Phd  in colorado school of mines and I am newbie in soil modeling  and I just started my PhD study  months ago. I am experimentally and numerically studying the stress distribution undernath the padfoot roller at the first stage, I need to have a constitutive model for soil with both dilatancy and hardening behaviors.

Fracture Toughness Anisotropy in Silicon Carbide

Submitted by Matt Pharr on

Here is a paper that I wrote my freshman year of college.  It discusses some observations about fracture toughness in a form of silicon carbide that had potential use in nuclear fission and fusion reactors.  It was published in the Department of Energy's Journal of Undergraduate Research.

ABAQUS/Standard - 2D beam elements vs 3D shell elements

Submitted by bilim on

Dear collegues,

I am modeling deformation of a simple triangular shape, /\, which is constrained at one end and the other end is free to move on the x direction. There is a displacement loading on the top corner and the output is the reaction force on the y direction at the free end.

 I used Abaqus/ Standard and modeled this problem in 2D beam elements and 3D shell elements. The material is aluminum with plasticity and nonlinear geometry is on.

Help with surface stress on microcantilever

Submitted by Lim Yang Choon on

Hi all,

I'm a PhD student with Electronics Engineering background. I'm doing a research in microcantilever based biosensors.

I'm having difficulties in understanding the adsorption-induced stress in microcantilever.

I would appreciate any advice or pointers on what materials that I can refer to. Besides that, what is the software that I can use to simulate this adsorption phenomenon? 

 

Thanks in advance.

 

Cheers,

Yang

 

please help for postbuckling analysis in ANSYS

I am trying to perform postbuckling analysis of plates in ANSYS. But something confuses my mind. After linear buckling analysis I use scaled firtst buckling mode shape to generate initial imperfections. Then I initiate nonlinear geometric analysis by NLGEOM command. Collapse load or final converged iteration changes according to NSUBST option. I am trying to give higher Substep to obtain more sensitive and reliable results like 10000. But NSUBST with 100 sometimes reaches higher loads than using 10000. Which one is a correct approach?

Could anyone help me?
