The singularities near the crack tips of homogeneous materials are monotone of type r α and r α log δ r (depending on the boundary conditions along nonsmooth domains). However, the singularities around the interfacial cracks of the heterogeneous bimaterials are oscillatory of type r α sin(ε log r ).

Strong solvability in the Sobolev space W 2 p is proved for the oblique derivative problem

## Abstract We consider a singular anisotropic quasilinear problem with Dirichlet boundary condition and we establish two sufficient conditions for the uniqueness of the solution, provided such a solution exists. The proofs use elementary tools and they are based on a general comparison lemma combi
By using an artiÿcial boundary an iteration method is designed to solve some elliptic boundary value problems with singularities. At each step of the iteration the standard ÿnite element method is used to solve the problems in a domain without singularities. It is shown that the iteration method is
We consider different types of singular boundary value problems for the Monge᎐Ampere operator. The approach is based on existing regularity theory and á subsolution᎐supersolution method. Nonexistence and uniqueness results are also given.
The singularity may appear at u s 0 and at t s 0 or t s 1 and the function f may be discontinuous. The authors prove that for any p ) 1 and for any positive, nonincreasing function f and nonnegative measurable function k with some integrability conditions, the abovementioned problem has a unique sol
