Hi,
I am working on implementation of non local damage mechanics model in abaqus using external subroutines, But in that case I have to modify the stifness matrix by adding the newly formed nonlocal stifness, Out of the available external subroutine options in abaqus documentation if any one gives the option to modify the tangential stifness matrix Please help me in the same.
Thanks and Regards,
Rohith
sir ,i ahve some problems in use ansys element CERIG,MPC 184 and RB3 elements....what is difference in transfering loads to slave nodes using MPC184 elements and command CERIG and RBE3 ..
and also why mass21 elements are required if u defining coonection usimg CERIg and RBE3 command..
plz...advice and clarify my doubts to understand better..
thanks and regards..

Hi all.
I am modeling a problem of a Double Cantilever Beam in Ansys 11.0,
using Exponential and Bi-linear Cohesive Laws.
For the Bi-Linear law, Ansys needs to introduce 6 constants, like the Critical Fracture Energy Gc, the normal stress σ...
The fifth constant, η, is the artificial damping coefficient, introduced to improve the convergence to solution.
Can you help me to understand the nature of this parameter?
Which values of this damping coefficient must be considered for a good modeling of the problem?
Two new papers grabbed my attention on my long unread list of journal tables of contents in Google Reader.
1) The first was
Ideomechanics of transitory and dissipative systems associated with length, velocity, mass and energy by G.C. Sih
where it is stated that
" One of the rules of the development of IDM is that the “flow of nature” takes precedent when deducting and/or constructing quantitative results. It is hoped that
I want to simulate the penetration into soil target, but I don't find the satisfied references about this simulation.The penetration into soil target will be simulated by the finite element method or meshless methods in my project. I think the good experimental results can verify the simulation.
Can you give me some references of penetration into soil target?
Thank you for your help.
Dear All,
I am a new user to MARC,could any one please help me by providing some input files(Example Problems) to learn Simulation starategy in MARC.I am also looking for Literature and any help in order to have sound knowledge of the software.
Thanks very much in advace,
