โœฆ Synopsis

The problem of implementing an essentially flnite solution of the arbitrary boundary condition homogeneous medium mathematical rupture problem in terms of elasticity linear theory is discussed. The relevant concepts taken as a principle solution with the infinite strain values in rupture tips cannot be dealt with by damage. mechanics. To abandon infinite solutions for crack tips means to dismiss such notions as stress intensity factor, surface energy and others which are the key parameters for damage mechanics. In terms of physics there is no difference between test piece extension fracture with necking and the effect resulting from a fracture. Namely, indefiniteness of fracture tip stress results in plurality of fracture considerations.

## Abstract The extended finite element method (XFEM) is applied to the simulation of thermally stressed, cracked solids. Both thermal and mechanical fields are enriched in the XFEM way in order to represent discontinuous temperature, heat flux, displacement, and traction across the crack surface,

Quadratic isoparametric elements which embody the inverse square root singularity are used in the calculation of stress intensity factors of elastic fracture mechanics. Examples of the plane eight noded isoparametric element show that it has the same singularity as other special crack tip elements,
