Abstract

In work results theoretical (numerical and analytical) and pilot studies of elastic stability are presented at compression of rectangular cores and the plates jammed on two cross-section edges, at a variation of ratios of the sizes and values of elastic constants. Degree of compliance of the numerical decisions received by a method of final elements, with data of analytical and experimental decisions for cores and rectangular plates is estimated. The formula for calculation of stability of plates for Euler taking into account Puasson's factor is presented.
