摘要: A new material degradation model only with fundamental properties required is proposed for composite progressive damage analysis based on micromechanics. For different failure modes, the effects of fiber and/or matrix are explored, from which factors these modes deduced. The then implemented analyses, using user subroutines in commercial code ABAQUS®, accompanying a modified Hashin type criterion and finite element models six commonly used double-lap bolted joints various layups, geometry dimensions, fasteners. numerical predictions loads, patterns, load–displacement curves compared results obtained static tests further ultrasonic C-scan detection. Good agreements between experimental outcomes indicate effectiveness suitability p...
