A type of gradient-degraded material-induced trigger has a greater potential to induce a progressive crushing mode in a controlled manner to reduce the initial crushing load and increase the specific energy absorption. Thus, different material degradation strategy-based triggers are designed to improve the crashworthiness of composite tubes. To understand the triggering mechanisms, effects of height of trigger and level of degradation are studied using single material degradation strategies. In turn, gradient material degradation strategies are novelly presented to explore different crushing behaviors of tube. Further, an improved gradient material degradation gathering all features of single material degradation and gradient material degradation is proposed. The virtual quasi-static crushing tests are conducted where the model considers intra-ply and inter-ply failure initiation and damage evolution. The crushing behaviors of all triggered tubes are compared. From the predicted results, it is found that both the height of trigger and level of degradation have significant effects on the crushing behavior. The multi-phased or progressive initial crushing process is presented by using gradient material degradation. By comparison, the tube using the improved gradient material degradation presents 8.26% lower peak load, 8.75% higher specific energy absorption, and 25% higher crushing load stability than the original tube.

“…For type II hybrid specimens, the failure was dominated by the compressive mode for the upper CFRP part while the tensile mode for the lower CFRP part. Since the critical fracture energy for compressive failure was higher than that for tensile failure mode, [ 31‐33 ] Type I hybrid specimens had relatively higher loading capacity than Type II and Type III hybrid specimens.…”

Metal/CFRP hybrid material system has been recently introduced as an effective alternative for automotive applications. This study aimed to investigate tensile responses and flexural behaviors of aluminum/carbon fiber reinforced plastic (CFRP) hybrid laminated plates by comparing with their counterparts made of net CFRP or aluminum materials. The experimental results showed that for the hybrid specimens the tensile strength increased and the tensile modulus decreased with increasing number of CFRP layers. Further, it was found that the bending indicators of the hybrid specimens were in between those of pure CFRP specimen and pure aluminum specimen. With the increasing number of CFRP layers, a reduction in flexural modulus could be observed in the hybrid specimens, while the flexural strength increased. A parametric study was further conducted numerically and it was found that tensile modulus was less influenced by the fiber stacking sequences when the number of 45° CFRP layers was the same, and both tensile modulus and tensile strength decreased with increasing number of 45° CFRP layers. Type II hybrid specimen, fabricated by upper and lower CFRP plates sandwiched with aluminum core, showed the lowest flexural modulus but the highest flexural strength. When the configurational scheme changed from symmetric distribution (type II) into Type I (fabricated by upper CFRP plate and lower aluminum sheet) or Type III (fabricated by upper aluminum sheet and lower CFRP plate), flexural modulus increased but flexural strength decreased. As for the Type II hybrid specimens, the flexural modulus decreased with increasing number of 45° CFRP layers.

The crushing behaviors of thin-walled composite structures subjected to quasi-static axial loading are comparatively evaluated using four different failure initiation criteria. Both available crushing tests of composite corrugated plate and square tube are used to validate the stiffness degradation-based damage model with the Maximum-stress criterion. Comparatively, Hashin, Maximum-stress, Stress-based Linde, and Modified criteria are respectively implemented in the damage model to predict crush behaviors of corrugated plate and square tube. To develop failure criteria, effects of shear coefficients and exponents in the Modified and Maximum-stress criteria on damage mechanisms of corrugated plate are discussed. Results show that numerical predictions successfully capture both of experimental failure modes and load–displacement responses. The Modified criterion and particularly Maximum-stress criterion are found to be more appropriate for present crush models of corrugated plate and square tube. When increasing the failure index, the crushing load is decreased, which also causes premature material failure. The shear coefficient and exponents have dramatic influence on the crushing load. Overall, an insight into the quantitative relation of failure initiation is obtained.
