Abstract

A series of nonlinear finite element analysis for unstiffened and stiffened plates with initial defect is carried out by ANSYS software. The ultimate strength of steel panels and stiffened plates with longitudinal through-thickness cracks under longitudinal compression is studied in this paper. The influence of mesh size, initial deflections of plate and stiffeners to ultimate strength is considered in the numerical analyses. Comparisons between the results by the paper and those from the experiment are made. The effects of crack position, plate thickness on ultimate strength are investigated and discussed for unstiffened plates. The different increasing values of the ultimate strength contributed by adding plate thickness, stiffeners with same steel weight, with crack either in plate or in plate-stiffener connection are compared. Finally, some conclusions are drawn with practical significance to engineering.
