“…The method has the potential to be combined with other in-plane damage theories (e.g. continuum damage models developed at the UBC Composites Group [27,26,12]), where intra-laminar damage is treated in a smeared manner, and the element stiffness is reduced gradually as a function of damage evolution within the finite element volume. Such methodology combines the numerical advantages of smeared modelling techniques with the need to model delamination in a discrete manner.…”

a b s t r a c tA novel technique for efficient simulation of progressive delamination in large-scale laminated composite structures is presented. During the transient analysis, continuum elements within regions where delamination has the potential to initiate are adaptively split through their thickness into two shell elements sandwiching a cohesive element. By eliminating the a priori requirement to implant cohesive elements at all possible spatial locations, the computational efforts are reduced, thus lending the method suitable for treatment of practical size structures. The methodology is verified here through its application to Mode-I, Mode-II and Mixed-Mode loading conditions for which benchmark solutions exist.

“…The simulated force‐displacement curve and damage failure morphology well agree with test results. McGregor et al predicted the energy‐absorption capacity of a braided composite square tube based on the continuum damage mechanics (CDMs) material model, and the numerical simulation results well agree with test results. However, their calculation results are more sensitive to the friction coefficient, fracture energy, and trigger mechanism setting.…”

This study aimed to investigate the energy absorption characteristics of glass fiber cloth‐reinforced epoxy resin (GFRP) composites. The axial dynamic impact test and numerical simulation study on 759/5224 circular tubes were conducted, as well as analyzed and discussed the relevant energy‐absorption parameters and failure morphology. Based on continuum‐damage mechanics, considering the anisotropic constitutive model of composites, the failure criterion including stiffness degradation was embedded into the second subroutine of MSC.Dytran platform and then introduced damage variables to update the material parameters. A progressive damage‐analysis model of composites with shear nonlinear effect was also established. Based on the improved secondary subroutine damage evolution model, the dynamic impact damage morphology of 759/5224 glass–fiber composite tube was accurately simulated; used the finite element simulation to obtain the absorption evaluation parameters of average load, special energy absorption and crushing stroke; and comparatively analyzed the simulation and test results. The maximum relative error of special energy absorption of the glass–fiber composite tube was <8.5%, which met engineering requirements. Therefore, the finite‐element method adopted in this paper can reasonably evaluate the gradual failure of dynamic impact of glass–fiber composite tubes. POLYM.

Numerical investigations were performed on a series of laminated composites when subjected to dynamic loadings, in order to determine their energy absorption rate and dissipating energy during impact. The details of numerical modeling, contact analysis, material parameters, and failure criteria were explained and discussed. We aimed to determine the energy absorption rate of various quasi-isotropic lay-ups when subjected to the dynamic loadings, and found that energy dissipation rate varied depending on stacking sequence. In this investigation, we studied how the energy absorption rate and the peak impact load change as a result of changing stacking sequence, with all stacking sequences being quasi-isotropic. Using a constant impacting mass and varied impacting speeds, we found that stacking sequence can significantly control the energy transfer rate or energy absorption rate under dynamic load condition.
