A novel micromechanics-based failure criterion for longitudinal compressive failure of fiber reinforced composites is proposed, taking into account two failure modes, fiber bending failure and inter-fiber shear failure, and judging them based on micro-scale stress. The validity of the failure criterion in predicting strength and failure mode is proved through micro-scale finite element models and existing experimental results. The key effect parameters of longitudinal compressive strength are also discussed. This proposed failure criterion can be applied in composite structures simulation and composite materials performance design.
A novel micromechanics-based failure criterion for longitudinal compressive failure of fiber reinforced composites is proposed based on the cross-scale stress calculation formula. Two failure modes, fiber bending failure and inter-fiber shear failure, are considered in the failure criterion, judged by the micro-scale stress inner fiber and inter fiber, respectively. The validity of the failure criterion on predicting strength and failure mode is proved by micro-scale finite element models and the existing experimental results. Final, the key effect parameters of longitudinal compressive strength are discussed. The proposed failure criterion can be used for composite structures simulation and composite materials performance design.
