An iterative approach to the solution of an inverse problem in linear elasticity

Ellabib, A.; Nachaoui, A. - In: Mathematics and Computers in Simulation (MATCOM) 77 (2008) 2, pp. 189-201

This paper presents an iterative alternating algorithm for solving an inverse problem in linear elasticity. A relaxation procedure is developed in order to increase the rate of convergence of the algorithm and two selection criteria for the variable relaxation factors are provided. The boundary...
