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.

Hi all,

When we do a non-linear buckling analysis, initially we introduce some imperfections (mode shapes of mode 1, 2 etc) from eigen buckling analysis. Then we multiply the load with eigenvalue of the first mode. This load is applied on the structure having imperfections. Now put on non-linear geometric option and run the analysis. At bifurcation point we get non-linear buckling load. Non-linear buckling load comes close to eigen buckling value.

Decription of my problem is as follows.
