Yield line theory application to a edge fixed disk by central load
Dear all,
I am trying to apply the Yield line theory to analyze the fracture of a disk by central load, F.
Do anybody know the yield line on the disk? I searched some books to find most references focus on rectangular plate rather than disk.
All suggestions are welcome. Thanks.

Hello IMechanicans,
I am interested in modelling shear response to mechanical stress at the interface of a two layer matrial e.g. the skin of the human hand, where the superficial layer of tissue slides over the deeper layer, while retaining some sort of attachment to it.
Does anyone know of any research papers that have investrigated this topic? I would rather base my work on the advances made my others, instead of reinventing the wheel.
Thanks,

3D Composite model in ABAQUS
Dear Abaqus Users,
I would like to model 3D composite structures using Hashin Damage model in ABAQUS. I have seen in ABAQUS manual that Hashin damage model is applicable only for shell element. I would like know whether I can use 3D element available in ABAQUS. Any help would be higly appreciated.

plastic analysis of a plate containing an edge notch and a piezoelectric inhomogeniety with ansys
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

question about binding reaction in surface of Microcantilever
As shown in the figure of Microcantilever biosensor,antigen solution flow into the cell, the banding reaction take place between the antigen and antibody. Wu research on the diffusion of molecules for long detection time (Wu, Datar et al. 2001), Berger elucidated the kinetics of stress curve for self-assembly as a simple adsorption isotherm.(Berger, Delamarche et al. 1998).
Rac activation by stress does not depend on Src
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.

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?
