Numerical modeling and analysis for axial compressive crushing of randomly oriented thermoplastic composite tubes based on the out-of-plane damage mechanism

Effect of the thickness on the fracturing behavior of discontinuous fiber composite structures

“…This aspect is significantly interesting considering the possible use of DFCs in applications demanding crashworthiness (see e.g. [22]).…”

Effect of the platelet size on the fracturing behavior and size effect of discontinuous fiber composite structures

“…It is found that the fracture energy of DFCs is much larger than several light alloys and always comparable to or larger than the quasi-isotropic laminate composite made from the same constituents. This aspect is significantly interesting considering the possible use of DFCs in the applications demanding crashworthiness [33].…”

Experimental method and evaluation for interlaminar shear properties of randomly oriented strand thermoplastic composites based on modified double-notch specimen and two dimensional digital image correlation

“…When crush tubes produced from ROS thermoplastic composites are subjected to an axial impact compression load, it has been shown experimentally that progressive failure occurs associated with interlaminar delamination of the wall surfaces, and the impact energy absorption is excellent compared with metal. Matsuo et al have succeeded 1 in developing a simulation model for axial impact crushing of crush tubes produced from ROS thermoplastic composites, with high reproducibility of the progressive failure mode and energy absorption associated with interlaminar delamination. This was achieved by providing a material model that takes into consideration the interlaminar shear delamination and fracture energy in cohesive zone elements of numerical simulation.…”
