i am not clear about implicit and explicit FEM
kindly let me know the difference of two and where to use which one

Help modeling a viscoelastic material in Abaqus

Hello,
I'm trying to model indentation of a viscoelastic material in Abaqus.
I have (1) stress-relaxation curves for the material and (2) force-displacement curves for the material from a real indentation experiment.
From this I can readily calculate the elastic modulus (infinite) and the elastic modulus (instantaneous) for the material.
I'd like to fit a Prony series based on this data that I can enter into Abaqus to model the material.
How would I go about fitting the Prony series from the force-displacement and stress-relaxation curves?

how to show the stress in the thickness direction when you use the shell element with abaqus
hello,
- i simulate some process using shell elment, i find the results have big difference between abaqus and lsdyna. the abaqus results always show the stress in the thickness direction is zero. but the lsdyna is not. i don't know why? if some one know that, please give me some suggestions. i heard that the abaqus can not show that stress component. if not, how can i do to calculate that and fill it into the results file (.fil file). thank you!
Problem with my Abaqus Double Layer Composite Identation Simulation

Hi everyone,
I currently using Abaqus/CAE 6.8. I currently doing my final year
project about indentation test on double layer composite material. The
top layer of the material is Pasta (elastic) and bottom layer is Gel
(hyperelastic). I manage to simulate the model and completed the
process. The stress of the Gel does not change as it undergoes
deformation. As shown in the clip i attached. Any idea to solve this
problem? Any suggestion is welcomed.. Thanks

Nonlinear Analysis
Hello,In order to nurture you in an effective manner regarding the Newton-Raphson method I recommend you to consult the excellent treatise of I. M. Smith et al. entitled "Numerical Methods for Engineers ", ISBN-13: 9781584884019.Furthermore this method is elegantly elaborated in Finite Element Formulation in the outstanding book of I. M. Smith indicated as "Programming the Finite Element Method ", ISBN-13: 9780470849705.In addition the geometrical nonlinear formulation is transparantly and completely detailed in the famous book of W. F. Chen et al.

I suppose it is acceptable to announce the work I have online to assist students in learning mechanics and thermo. The site is http://www.askdrthermo.com/. Please take a look if you are interested.
