Probabilistic multiple cracking model of elastic-brittle matrix composite reflecting randomness in matrix, reinforcement and bond

Popis výsledku v původním jazyce

The paper describes a semi-analytical multiscale model of the tensile response of unidirectional brittle-matrix composites with heterogeneous reinforcement. A probabilistic multiple cracking model is proposed, and we apply a probabilistic crack bridge model to simulate the behavior of a representative crack bridge within proposed model, which simulates the strain-hardening response of a multiply cracked composite subjected to tensile loading. In order to reflect the random nature of matrix cracks emerging during the loading process, we apply the random strength approach and represent the matrix strength by a random field. A robust algorithm is formulated for determining initiation loads and positions of matrix cracks for an arbitrary formulation of the fiber-matrix interface. The developed model is calibrated and validated against experiments with textile reinforced concrete.
