Low velocity impact behavior of interlayer hybrid composite laminates with carbon/glass/basalt fibres
TL;DR: In this paper, the effects of hybridization and fabric structure on the impact resistance of composite laminates were investigated and a continuum damage mechanical model was developed and validated for non-hybrid woven fabrics at different impact energy levels.

On crashworthiness design of hybrid metal-composite structures
TL;DR: In this article, a finite element (FE) model was developed and validated by comparing the damage modes and crashworthiness indictors with the dedicated experimental study, and the interactive effects of the hybrid tubes were investigated by analyzing the discrepancies in the deformation pattern and internal energy absorption of each material through validated FE models.

Finite element analysis of a modified progressive damage model for composite laminates under low-velocity impact
TL;DR: In this article, a 3D finite element model is established in ABAQUS/Explicit based on a modified progressive damage model to study the dynamic mechanical response and damage development in cross-ply composite laminates subjected to low-velocity impact.

Damage accumulation mechanism of composite laminates subjected to repeated low velocity impacts
TL;DR: In this paper, the repeated low velocity impact responses and damage accumulation mechanism in the composite laminates were investigated by considering the effect of impactor diameter, and the delamination projected area was measured using ultrasonic C-scan during the whole-process repeated impacts.

TL;DR: In this article, an operationally simple strength criterion for anisotropic materials is developed from a scalar function of two strength tensors, which satisfies the invariant requirements of coordinate transforma tion, takes into account the difference in strengths due to positive and negative stresses, and can be specialized to account for different material symmetries, multi-dimensional space, and multi-axial stresses.
