Abstract
In this paper, the simultaneous identification of the Poisson ratio, the shear modulus and a circular cavity embedded in an isotropic linear elastic material from boundary measurements is investigated. The numerical method proposed is based on the least-squares minimisation of the errors between the measured and the calculated tractions on the outer boundary using the boundary element method (BEM).
