I thought the mechanics community would be interested in the course notes of
Prof. K. J. Bathe on "Finite Element Analysis of Solids and Fluids". This
course was taught at MIT and now is available freely through MIT Open
CourseWare website:
Enjoy!
Hello
What is Lumped Mass in Dynamic Analysis,its Significance?Can anyone suggest its definition please.How do we create it in LS-Dyna.
During the study of FEM, I found the term "weak form" of differential equation, which is the integral form of a differential equation along with the boundary conditions for a boundary value problem. Now my question is that why the term "weak" has been used.
Hi all,
Can anyone explain me the characteristic features of continuum mechanics, micromechanics and nanomechanics? My present level of understanding is:
Hi,
how do I Determine Z axis ( blue axis ) of the element coordinate ( with solid46 ) in outward Direction .
in Attached file put the cross section of the Model .

These are slides of poroelasticity and diffusion in elastic solids for final presentation based on ES241 notes.
These slides are based on an on-going paper written by Wei Hong, Xuanhe Zhao and Zhigang Suo and Suo's talk in ucsb.
I am trying to implement an analytic formulae of dynamic flow stress in material plasticity in abaqus. The model is similar to FlowStress=K*(PlasticStrain^n)*(StrainRate^m).
Could you provide help for these 2 questions?
1: Is it OK to define Young's modulus (E) and v in "Elastic" and choose "User" in "Plastic-->Hardening" with the subroutine "VUHARD", instead of by "VUMAT" with plasticity criterion and calculation of delta stress and strain?
sir
can i find natural frequencies of cracked rotating shaft in ansys.i am using contact elements to model crack due to which nonlinearity comes into picture.since modal and harmonic analysis cannot solve nonlinear problems,so please tell me in detail the steps to find natural frequency .
my project submission date is on 15th june and i have no results.pls reply as soon as possible
it will be yr great help.
thanks in advance
