Project

Global analysis methods for slender structures of stainless steels and other steels with non-linear stress-strain diagram (GA20-24563S)

Modern steel material (e.g. stainless steel, HSS) exhibit significant degree of stress-strain nonlinearity affecting member behaviour significantly. The presented project proposal deals with development of methods for accurate descr...
