Finite difference method for elasticity
I am trying to solve elasticity equations by Finite Differnce Method using matlab. i am feeling some problems in applying external loading in form of distributed load. i have discritized the displacemet equation but unable to apply distributed laoded in form of deformation. Can some one help me how to apply stress boundry condition (neumann BC)?

As an issue far from being settled, the analysis of short cracks has always many difficulties.
1, First of all, which method can be used to describe the short crack behavior?
non linear buckling analysis on a pipeline using ansys
Hi,
I am doing buckling analysis of a pipe with liner inside it. I did eigen buckling on the problem. buckling pressure from my calculation is 15.83Mpa and from ansys it is 15.19Mpa, so I am pretty happy with that. But i would like to do nonlinear buckling analysis on the same problem as a part of my project.
can anyone suggest how to do it using ansys 12,mechanical apdl
Thanks

Hi,
I've been learning how to implement material models using UMAT in ABAQUS and I have
some simple questions:
I've been trying to implement the viscoelastic models in the paper:
Formulation and implementation of three-dimensional viscoelasticity at small and finite strains
Kaliske, M.; Rothert, H., Computational Mechanics, Volume 19, Issue 3, pp. 228-239 (1997) .
1) The variable "STRAN" in UMAT corresponds to the strain at time $t = t_n$ or $t = t_(n+1)$,
how to mesh AC3D4 acoustic tetrahedral

im working on an abaqus model which should be meshed by AC3D4 acoustic tetrahedral elements.
i attached the picture of main meshed model and my model .
but there is a difference between them. ( i pointed them by white areas)
how can i mesh o control mesh to create that kind of meshing
top model is mine and bottom is original model.
tnx
