Estimates and Asymptotics for the stress concentration between closely spaced stiff inclusions in linear elasticity
Yu Chen, Haigang Li
This paper is concerned with the stress concentration phenomenon in elastic composite materials when the inclusions are very closely spaced. We investigate the gradient blow-up est…
