Dear Colleagues,
We are pleased to inform you that at the conference Inverse Problems, Design and Optimization Symposium (IPDO) that was held in João Pessoa, Brazil from 25-27 of August, 2010 the results of application of IOSO optimization software were presented for a new complex class of optimization problems: Design of Molecules.
hi i am ganesh
currently we are doing final year project about process modelling of turning operation in ansys lsdyna.we are facing difficulty in finding out the constants required for the johnson cook material model.chip formation and failure criteria is still a major problem.so i kindly request you to give suggestion and materials to solve this problem.

Dear friends
Can you help me to find the relationship between true (Cauchy) stress and Almansi strain (constitutive equation)?
thanks

I am working on crack propagation analysis of lamellar microstructures using XFEM. everything is working fine but i have an annoying observation that whenever i change the damage stabilization parameter let say from 1e-5 to 1e-6 then the force-displacement curves changes abruptly and the force which i am measuring on a reference node of my indenter varies two to three times. i tried to see if damage stabilization parameter effect the F-D curves and i observed that crack length and F-D curve changes.
It is essential to know the amount of springback for a given forming process, so that the process or the design of the tool can be modified to obtain the desired product shape. This requires a comprehensive understanding of loading and unloading processes, and determination of elastic constants with finite plastic deformation which, in turn, require precise determination of subsequent yield surfaces.
We call for contributions from mechanics community to 2011 MRS Spring Meeting Symposium Z: Nanoscale Electromechanics of Inorganic, Macromolecular, and Biological Systems
The abstract submission is open until Nov. 2, 2010, at http://mrsspring2011.abstractcentral.com/
More information about the symposium, including a list of invited speakers, can be found at
I have some problems with my matlab code in a 9 node shell
element each node has 5 DOFs. I found that stiffness matrix for each
element is symmetric, but after transformation to global coordinate
system, the transformed stiffness matrices and the resulted global
stiffness matrix of entire shell is nonsymmetric, where order of
transpose([k]) -[k] is approximately E-18.
Mass matrix also has
been antisymmetric after transformation and so I can't solve
characteristic equation to find eigenvalues needed for dynamic analysis.
