Abstract
Numerical analysis of the analytic model of an experimental procedure to determine the crack length, the compliance and the energy release rate has been developed. As a first step, bending tests at different spans have been numerically simulated with the purpose of obtaining the flexural and out-of-plane shear moduli of the material. Then the crack length has been determined from the numerical compliance, considering the material properties previously obtained. The critical energy release rate has also been determined analytically and numerically. There is agreement between the numerical results and those obtained from the analytic model of the experimental procedure.
