Dear Friends,

The reputed Springer publication from The Netherlands has given me the responsibility to edit a book titled “Nanomechanical Analysis of High-Performance Materials”.

Hi,

I am trying to analysis a model in ABAQUS with a plate bolted to the Bracket top surface at 4 ends. I have to define contact between them (and also bolted at 4 ends) to get the Modal frequency. But When I searched for it, I got the answer that contact doesn't work with Modal analysis as contact is a nonliner problem and Modal Analysis only solves linear problem.

While reading the article

"An alternative approach to finite plasticity based on material isomorphisms " (1999) by Prof. Bertram, the first thing that attracted my attention was the quote [by Prof. Naghdi (late)]:

 “there is some degree of disagreements on nearly all of the main constitutive ingredients and features of plasticity in the presence of finite deformation... Some of the issues of disagreements are of basic and fundamental importance.”

I present in this note a finite difference method and Scilab computer programs to

numerically solve the Saint-Venant theory for torsion of prismatic beams (shafts, bars) of

piecewise rectangular cross section. The purpose of this note is mostly educational, for I

believe that it is quite instructive to not only solve these problems analytically whenever

possible but also explore solutions numerically of common configurations for which one

cannot readily obtain analytical solutions. The same kind of problems occur in heat transfer,

Hi,

Do anyone know how to introduce ovality into a circular model in ansys.

Thanks
