pure shear

Many people puzzle over the nomenclature of the pure shear test. They rightly point out that 1) the Pure Shear test piece is loaded in tension by extending the specimen in the axial direction, and 2) a shearing deformation, by definition, involves the lateral motion of parallel planes. They wonder where is the "shear"? and what does it mean to say that the shear is "pure"? Here, we review the origins of the terminology.

Can anybody suggest a good beginners book in micromechanics? I recently started working on ceramics and relatively new in this field. thanks.

Buckling and Post buckling

Can anyone help me out to resolve DMAP Fatal Message 9061(IFPL) - the version requested on the restart FMS statement is not valid for restart purposes. subsequent restarts should reference a prior valid version.

What this error and why it is happening?

Thanks in Advance

geometric imperfection of a localized buckling behavior of unstiffened thin plate

research

i'need to initial geometric imperfection of a localized buckling behavior of unstiffened thin plate will be analyzed. Code Abaqus finite element analysis can be used for this purpose. Since a default is not always in isolation, the interaction between several localized defects will be considered. A parametric study will be conducted on the effect due to the interaction by using an experimental and numerical analysis of variance.

thank you.

Finite Volume Method

Submitted by smitra on Sat, 01/21/2012 - 01:36

I am seeking advice on the capability of using Finite Volume Method to solve Hyperelastic Solid deformation. Can anyone help me to get a proper direction to analyze very large deformable structural problems?

Thanks,
