Damage propagation in a masonry arch subjected to slow cyclic and dynamic loadings

摘要: In the present work, damage propagation of a masonry arch induced by slow cyclic and dynamic loadings is studied. A two-dimensional model proposed. nonlocal damage-plastic constitutive law adopted to reproduce hysteretic characteristics material, subjected static or harmonic excitations. particular, cohesive able take into account different softening laws in tension compression, plastic strains, stiffness recovery loss due crack closure reopening. The latter effect an unavoidable feature for realistically reproducing cycles. studied case, inverse procedure used calibrate parameters. Then, nonlinear responses are described together with paths.
