“…In the paper [14] presents a model of CFRP that takes into account elastic-plastic damage and the behavior of the material in the experiment corresponded to the presented model. The behavior of fiberglass at relatively low interaction rates is presented in [15], in which a numerical analysis of the impact of an aluminum particle on a CFRP object using SPH method is carried out.…”

Numerical simulation of the impact of an aluminum particle on a composite medium was carried out. Carbon fiber reinforced plastic (CFRP) laminates T300/69 were used as a research object. The behavior of CFRP was analyzed at an impact velocity of 11 km/s and an aluminum particle mass of 1 g. The composite layers were located in planes oriented perpendicular to the direction of reinforcement. The Smoothed-particle hydrodynamics (SPH) method in conjunction with Ansys Autodyn was used for numerical modeling. Since large deformations and fracture of the objects were observed at such high impact velocities, which indicated a violation of the continuity of the material, that makes it incorrect to use of traditional mesh methods. The dependence of the shock wave propagation velocities in CFRP on time was obtained. The minimum thickness of the protective screen made of CFRP was estimated.

“…Nevertheless, the influence of different geometry and load parameters on the type and area of occurring damages have been also investigated. The following exemplary paper could be mentioned: (i) the influence of impact position on damages have been investigated by Sun and Hallett [17], (ii) the effects of ply clustering on polymer-based laminated composite plates subjected to impact load have been considered by Gonzales et al [18], (iii) the influence of layer arrangement, impact energy, and ball velocity on damage area, strain in time relation, delamination area vs. impact energy in the case of single impact and multiple impacts based on not standard specimen dimensions (i.e., panels 900 mm × 1100 mm) were tested by Nassr et al [19], (iv) the influence of impact energy and impact force on delamination area of GFRP plates with rectangular and circular shape have been investigated by Cantwell [20]. (v) Further, the influence of drop off configuration on impact load response have been analyzed by Abdulhamid et al [21], (vi) Shyr and Pan [22] showed multi-elements analysis of impact resistance of fiber glass composite materials, (vii) the tensile tests on initially pre-damaged thin-ply angle-ply pseudo-ductile carbon fiber laminates have been investigated by Prato et al [23], (viii) Gliszczynski et al [24,25] investigated the low velocity impact damages in plate and channel section profile on size and shape of damage with comparison to standard CAI tests.…”

The paper deals with buckling, postbuckling, and failure of pre-damaged channel section beam subjected to pure bending. The channel section beams made of eight-layered GFRP laminate with different symmetrical layups have been considered. The specimens with initially pre-damaged web or flange were investigated to access the influence of impact damage on work of thin-walled structure in the full range of load till failure. The bending tests of initially pre-damage beams have been performed on a universal tensile machine with especially designed grips. The digital image correlation system allowing to follow the beam deflection have been employed. The experimentally obtained results are presented in graphs presenting load-deflection or load vs. angle of rotation relations and in photos presenting impact damages areas before and after bending test. The results show that the impact pre-damages have no significant influence on the work of channel section beams.
