Contact issues in abaqus
Hi All,
I am dealing with contact problems. Can you please post if you have any information on how to resolve the general contact problems.
thanks and Regards,

Virtual Heart Surgery
1. We highlight a study performed by researchers using ADINA in which they investigated a computational approach to construct patient-specific ventricle models based on in vivo cardiac magnetic resonance (CMR) imaging for surgical planning and optimization. The study was motivated by the fact that the use of such computational models can help to assess different surgical hypotheses and replace empirical and perhaps risky clinical experimentation.

Hello Everybody,
A wing was simplified with 8 dumbbelss or concentrated mass. The weight of the 8 dumbbells are:
{W}=[1.240 1.050 0.964 0.862 0.733 0.628 0.634 0.457]T
The static unbalance is:
{SA}=[0.2680 0.2910 0.1810 0.1610 0.1220 0.0884 0.0854 0.0598]T
The moment of inertia is:
{IA}=[0.412 0.437 0.272 0.230 0.157 0.143 0.115 0.055]T

Good morning
I'm working in Abaqus on drying modeling. Regards this i have two questions.
1)Drying modeling is possible in Abaqus
2)I would like to ask if it is possible for Abaqus to model drying how can i create automatic crack propagation in 2D or 3D
P.S. sorry for my english, i hope everything is clear enough to understand this post. i hope someone can help me.

A Field Theoretic Approach to the Quasi-Continuum Method
Dear Colleagues,
I wish to bring to your attention my recent work with Mrinal Iyer on a field theoretic approach to the quasi-continuum method to appear in Journal of the Mechanics and Physics of Solids. Below is the abstract and attached is the preprint of the article. I will very much appreciate your comments and suggestions.

The mechanical performance of H-shaped NCF adhesively bonded joints
Adhesive bonding is contemplated as an alternative method to mechanical fastening for joining composite aerostructures.
Ongoing research in this area is focused on the development of new bonding techniques and joining elements. In this
article, the mechanical performance of the novel noncrimp fabric (NCF) H-shaped adhesively bonded joints subjected to
tension, shear and four-point bending loading conditions was investigated by both experimental tests and numerical
How to model a layer of thermo setting polymer in abaqus?
Dear all, I am modeling a 3 plies plywood using abaqus. I am facing some problem in modeling the resin layer which bond the wood veneer. Does anyone know how to model a layer of thermo setting polymer in between 2 ply of long grain direction wood veneer? Many thanks!
How to understand the shear modulus of polymers
Hi everybody,
I have a question about the shear modulus of polymers. As we know, the general engineering polymers （rubbers） are highly extensible and elastic. The shear modulus，G， for the polymers subjected to the small-strain conditions, can be defined by G=NkT, where N is the number of network chains, k is Boltzmann's constant and T is temperature in Kelvins.
