Abstract

Stiffness with loss of material

Submitted by vishnusworld on

Dear All

I am modeling a workpiece supported in fixtures and being machined. I use the FEM ( Ansys) to simulate this set up. I need to know at the stiffness of wp at the wp-fixture contact point  . Stiffness is found by applying unit force at one contact point while fixing all others.. Inverse of displaceemnt gives the stiffness in that direction. I have two questions reg this.

Nonlocal Damage implementation using ABAQUS UEL

Submitted by hadi on

Hi everyone,



In order to simulate nonlocal damage in trabecular bone structures in
ABAQUS, I need to implement the constitutive laws into the user element
subroutine (UEL), since it is not possible to implement nonlocal FE in
UMAT, as far as I know!



I would be very much grateful if someone, who has experience in this
regard, esp how to implement 3D elements, e.g. C3D8, into a UEL code,
shares some knowledge.



Best,



Hadi

Paper by Ellad Tadmor & Nikhil Admal---Atomistic Definition of Stress

Submitted by Pradeep Sharma on

For both mechanicians and physicists, linking continuum concepts to the underlying microscopic characteristics of materials has remained a major preoccupation. Certainly, with the recent advent of the so-called "multiscale" modeling approaches, this topic has been brought to a sharp focus. Cauchy stress is one such continuum concept that has courted a fair amount of controversy.
