摘要: Abstract The deformational response of [±θ/904]s laminates under longitudinal tensile loading is treated by a synergistic approach that combines continuum damage mechanics (CDM) and micromechanics. constraint θ° plies on transverse cracks in 90° represented crack-opening displacement (COD) parameter the CDM model expressed terms ply properties thickness ratios basis finite-element calculation. A methodology proposed for predicting laminate stiffness variations with crack density applied strain (or stress) various values orientation θ found to give good results.
