Stability of a kind of welding problem under different materials with same shearing modulus. (English) Zbl 1313.74023
Summary: This paper discusses the stability of the welding problem under different materials with same shearing modulus. Using the stability of Cauchy type integral while the smooth perturbation for the integral curve and Sobolev perturbation for the kernel density happening, the stabilities of complex stress functions are studied and errors of stress and displacement are given.
