The plane stability problem for a rectangular, linearly elastic, isotropic plate with a central crack is solved. The dependence of the critical load on the crack length is studied using exact (the three-dimensional linearized theory of stability of elastic bodies) and approximate (beam approximation) approaches. The results produced by the beam approach are evaluated.Translated from Prikladnaya Mekhanika, Vol. 40, No. 11, pp. 117–126, November 2004.This revised version was published online in April 2005 with a corrected cover date. 相似文献

The paper studies the three-dimensional stability of an isotropic, linear elastic, rectangular plate under a uniform tensile
load applied to its sides. The concept of free strains is used to reduce the three-dimensional problem to a two-dimensional
one. It is solved using the three-dimensional linearized theory of stability. An approximate solution of the buckling problem
is obtained by the finite-difference method. Numerical results are presented

The piecewise-homogeneous model and the three-dimensional linearized theory of stability for small subcritical strains are
used to study the surface instability of a regularly layered rock mass under biaxial loading. A plane problem is formulated.
Basic characteristic equations are derived. A specific problem is solved as an example to demonstrate the selection of loads
and the interaction of support elements with the wall rock

Models in the theory of stability of multiwalled carbon nanotubes in a polymer matrix are justified. Some results on the fracture
mechanics of nanocomposites are presented. New areas of research in mechanics suggested by a group of well-known scientists
are discussed
