Expansion-compression fixed point theorem of Leggett-Williams type for the sum of two operators and applications for some classes of BVPs [PDF]

, 2023
The purpose of this work is to establish an extension of a Leggett- Williams type expansion-compression fixed point theorem for a sum of two operators. As illustration, our approach is applied to prove the existence of non-trivial, nonnegative solutions ...

Multi-parameter approximation of stress field in a cracked specimen using purpose-built Java applications [PDF]

Fracture and Structural Integrity, 2015
A quality of multi-parameter approximation of the stress and displacement fields around a crack tip in a non-brittle material test specimen is studied in the paper. The stress field approximation using Williams power series is intended to be utilized for
