The main results of research on some nonclassical problems of fracture/failure mechanics
are analyzed. These results have been obtained by the author and his followers at the …

A new alternative approach to fracture problems for materials and structural elements with
cracks is set out. It is based on the mechanism of local instability near defects. The approach …

Introduction. Prediction of the technical cohesive strength of elements containing cracks
plays an important role in the design of modern machinery. The importance of this aspect of …

The half-space with an infinitely deep crack being considered is loaded by its own weight
and is subjected to the actionofa uniform force field at inifinityin the oxy plane and in planes …

The phenomenon of local loss of stability in thin plates with cracks under tension has
already been rather thoroughly studied. The results of these studies were presented in …

Following [2, 3], the present work undertakes to solve the problem of determining the critical
stress corresponding to local stability loss of a plate with a crack in an accurate formulation; …

The results for AMg-6M with t= 0.47 mm and I/b= 0.4 indicate that 6 is also substantially
affected by 2/; eg, for a plate with 2b= 250 mm and 21= i00 mm, which implies I/b= 0.4, we …

It is apparent from the table that satisfactory agreement between empirical and calculated
values is seen beginning with the ratio 1/b~ 0.3 for a sheet of thickness t= 0.93 mm at=~/4 …

When external forces are absent, the body is in a state of equilibrium which is described by
equations of classical elasticity theory and is called subcritical. This assertion remains …

Investigations of the stability of the state of equilibrium of the lower half-space near vertical
cracks on the basis of the three-dimensional linearized theory [1, 2] are of interest in …
