Progressive Damage Modeling of Composite Materials Under Both Tensile and Compressive Loading Regimes

Characterization of strain-softening behavior and failure mechanisms of composites under tension and compression

“…The over-height compact tension (OCT) test geometry (Fig. 5a), developed by Kongshavn and Poursartip [15] was used. In this study, a sharp notch with a notch tip radius of approximately 1 mm was cut in all the specimens.…”

“…[1][2][3][4][5][6][7][8] and compression [e.g. [6][7][8][9][10][11][12][13][14][15] have been investigated. It has been shown that the sequence and evolution of these failure mechanisms may vary depending on various parameters, including the laminate stacking sequence or the lamina thickness [4].…”

“…Under compression, it has been shown that the kink band formation process is the main failure mechanism in unidirectional composites and a combination of kinking, delamination and matrix cracking constitute the main failure mechanisms in multidirectional composites [e.g. [5][6][7][8][9][10][11][12][13][14][15][16][17]. All of these failure mechanisms contribute to the loss of material stiffness and subsequently loss of structural load bearing capacity.…”

Comparison of Tensile and Compressive Properties of Carbon/Glass Interlayer and Intralayer Hybrid Composites

“…In addition to the fiber investigation, some researchers studied the tensile and compressive properties of composites. Zobeiry et al [ 23 ] developed a model to explain the failure mechanism of composite under tension and compression, where the tensile failure is mainly due to the kink band, which is the reason for the formation of fiber failure and resin fracture or yielding. The ratio of tensile and compressive strength of flax and bamboo composites was found to be 60%, and the compression properties of coir fiber composites were even better than the tensile properties [ 24 ].…”

Simulation of the Mechanical Response of Thin-Ply Composites: From Computational Micro-Mechanics to Structural Analysis

“…This usually leads either to too simplistic analytical solutions or computationally demanding numerical models. However, the recent computational advances allowed numerous published demonstrations of successful representations of the initiation and propagation of damage in composite materials at different length-scales, from detailed constituents (micro-mechanical ) representations [12, 17, 41, 81, 95, 119-122, 166, 169-171, 184, 185], to homogenised models at the ply-level (mesoscale) [2,34,37,94,111,112,154,179,180,198] and at the laminate-level (macroscale) [6,57,58,143].…”
