A synergistic damage-mechanics analysis of transverse cracking in [+/-theta/90(4)](s) laminates Academic Article uri icon

abstract

  • The deformational response of [/904]s laminates under longitudinal tensile loading is treated by a synergistic approach that combines continuum damage mechanics (CDM) and micromechanics. The constraint of plies on transverse cracks in 90 plies is represented by a crack-opening displacement (COD) parameter in the CDM model and is expressed in terms of the ply properties and ply thickness ratios on the basis of a finite-element calculation. A methodology is proposed for predicting the laminate stiffness variations with crack density and applied strain (or stress) for various values of ply orientation and is found to give good results. 2001 Elsevier Science Ltd.
