Cyclical Nanoindentation Stress-Strain Measurement
The Stress-Strain curve obtained by Nanoindentation reveals the correlation of "Stress" and"Strain" of a given material under nano controlled loads. Unlike the traditional Tensile Testing method of obtaining Stress-Strain curve data, which gives data at a macro level, the Nanoindentation method provides vital Stress-Strain curve data at nano level scale without the large and intense machinery. The Stress-Strain curve of various materials will vary widely.
Analysis Buckling
Can you help me, I have trouble solving buckling analysis, can you help me to provide references / examples of solving buckling analysis steps on a space truss structure.
thanks

Inverse problem in beam bending, elastic-ideally plastic material
Dear iMechanica,
suppose you have a beam with a square cross-section, manufactured from an elastic-ideally plastic material.
Now apply a load that rises linearly in time, but is locally constant along the beam length. Upon sagging, the beam will develop a plastic zone beginning in the top and surface regions at mid-length.
This is the "straight" problem solved in Prager, Hodge: Theory of perfectly plastic solids, publisher: Springer
Delamination and Cohesive zone model
I want to work on delamination and cohesive zone model. I would also like to model this in Abaqus. I’ve read the material available there but it’s not adequate. I would like to know the concepts and fundamentals of the cohesive zone model and its implementation. Can anyone explain this? Please suggest some good literature/books on this for beginners.
Praveen.
Siple Compression Test With Abaqus Explicit
Hi, i am trying to test a bulk metallc glass VUMAT with a simple compression test simulation. But since VUMAT is a Abaqus Explicit subroutine, that means I must set my compression simulation with setting of Abaqus Explicit right? So far I only have the experience in conducting compression test simualtion using ABAQUS Standard setting like static general step and surface-to-surface contact (standard). I don't know how to set up a simple compression test simulation with Abaqus Explicit settings, can anyone help me please?
Thanks and regards.
