I have to analyse the carbon/epoxy composite laminate in ANSYS, to determine the natural frequency of rectangular composite plates. The plate is simply supported . I am not able to model the composite lay up with the correct orientation of the fibre. so any body have the step by step procedure for modelling the composite lay up in ANSYS and how to determine natural frequencies please give it to me on my e-mail: sharma_avadesh [at] yahoo.com
Hi,
I am rojin ghandriz,study M.c civil engeeniring at sharif university in iran,
I study on my tesis a bout plastic analysis of a plate containing an edge notch and a piezoelectric inhomogeniety.
I have questions a bout the crack initiation in Ansys v11.0..How could i get initiation of crack whit increasing tensile loading on plate in ansys?
thanks
rojin
It is known that platelet derived growth factor (PDGF) induced Rac activation depends on Src activity. However, we find that a local stress of physiologic magnitude via integrins can directly activate Rac GTPase rapidly, independent of the Src activity. Our finding on the stress-induced rapid Rac activation challenges the conventional wisdom on mechanotransduction and suggests that stress-induced signaling via focal adhesions does not follow signal transduction pathways induced by growth factors.

Two post-doctoral researcher positions focusing on the two topics listed below are available immediately at Research Center for Applied Sciencs at Academia Sinica (中央研究院) in Taipei, Taiwan.
1) Ab initio MD simulations of Li ion diffusion on / inside novel electrode materials using accelerated MD. Candidates with expertises in ab initio MD, in particular, BOMD, are highly desirable.
Dears,
I'm doing some numerical analysis on penetration of infra-strucutres on soils (such as CPT tests) in ABAQUS/CAE .. what I'm recently challenging with is to overcome the element excessive distorsion due to large deformations... I have to apply contact constraints in my model...I would appreciate it if you share your expriences with me regarding the following tips:
1- Is it possible to use the ALE (Arbitrary Lagrangian-Eulerian) mesh adaptivity in ABAQUS/Standard? If yes, do you know of any accessible examples (.cae files) or references?
We present an application of ADINA in the thermo-mechanical analysis of friction welding. Please see:

I am confused about the use of two-point tensors in elasticity. The deformation tensor F and first PK tensor are two point tensors, and the "two-point" property arises from use of two different Coordinate System When a continuum body is deformed, why it is necessary to move the Coordinate System as well? (or alternatively, why the coordinate system is attached to the body itself??, isn't it possible to use a general coordinate system which can represent the deformations and also account for the rigid body rotations of the continuum body?).
