3D finite element modeling of yarn reinforced mineral matrix: Comparison of damage behavior with experimental data

Mineral-based composites are presented as a real alternative to the use of Fiber Reinforced Polymer (FRP) composites. However, most studies have focused only on global mechanical behavior mineral-based The objective this paper is develop 3D numerical model in order predict and local tensile glass yarn/ettringitic matrix Two configurations been studied including dry pre-impregnated yarn. This modeling based microscopic approach that considers composite heterogeneous material, requires defining properties matrix, yarn interface. To simulate cracked yarn- bond, discrete cohesive zones was adopted. For both composites, comparisons experimental results showed good agreement terms behavior, cracking failure mode. allowed analyze stress strain states yarn, interface therefore deepen knowledge type understand mechanisms act during evolution test.
