A Levenberg-Marquardt algorithm for fi tting σ-w curves from three-point bend tests for plain and fi ber reinforced concretes

This technical note describes the implementation of the Levenberg-Marquardt algorithm for the inverse analysis of three-point bend tests on notched specimens of plain and fiber reinforced concretes for determining softening parameters (σ-w curves). Tests indicated that the algorithm is sufficiently...

description This technical note describes the implementation of the Levenberg-Marquardt algorithm for the inverse analysis of three-point bend tests on notched specimens of plain and fiber reinforced concretes for determining softening parameters (σ-w curves). Tests indicated that the algorithm is sufficiently efficient and robust.
