Phase-field fracture simulations have been established to simulate crack propagation in solid structures. The method employs a variational framework which has proven converge Griffith' classical model for brittle fracture. Here we investigate the predictiveness of phase-field through four-point bending test mixed mode condition, and discuss possibilities perform such simulation with finite elem...

The presented research introduces a new Ionic Polymer-Metal-ZnO Composite (IPMZC) demonstrating photoluminescence (PL)-quenching on mechanical bending or application of an electric field. The newly fabricated IPMZC integrates the optical properties of ZnO and the electroactive nature of Ionic Polymer Metal Composites (IPMC) to enable a non-contact read-out of IPMC response. The electro-mechano-...

The present paper is devoted to fracture analysis of an inhomogeneous non-linear elastic beam configuration with three parallel longitudinal cracks. material continuously along the height. subjected four-point bending. behavior studied by applying J-integral approach. Solutions are obtained for For this purpose, curvature and coordinates neutral axes crack arms determined using equations equili...
