TLDR
In this paper, an F.E. semi-continuous explicit model has been developed to identify the mechanisms of damage to the skin for different orientations of the firing axis and to develop a representative model of the damage kinetics adapted to the modeling of the complete structure.About:

Journal ArticleDOI
Parameters influencing the impact response of fiber-reinforced polymer matrix composite materials: a critical review
TL;DR: In this paper, a comprehensive review on the four key parameters specifically material, geometry, event and environmental-related conditions that affect the structural behavior of fiber reinforced polymer matrix composites to impact loading is discussed.
Journal ArticleDOI
The oblique impact response of composite sandwich plates
TL;DR: In this paper, the authors focus on the experimental study of low-velocity oblique impact on composite sandwich plates and select several impact angles and impact energies to study their influence on the maximum contact force, maximum contact time, absorbed energy, maximum displacement of the impactor, and damaged area.
Journal ArticleDOI
A comprehensive review on material selection for polymer matrix composites subjected to impact load
TL;DR: The application of multi attributes decision making (MADM) tools is demonstrated for selection of fiber and matrix materials which can serve as a benchmark study for the researchers in future.

Energy absorption characteristics of additively manufactured plate-lattices under low- velocity impact loading
J. Jefferson Andrew,Johannes Schneider,Johannes Schneider,Jabir Ubaid,R. Velmurugan,N.K. Gupta,Shanmugam Kumar,Shanmugam Kumar +7 more
TL;DR: In this paper, the impact response of 3D plate-lattices fabricated via stereolithography additive manufacturing (AM) was analyzed. And the impact energy, relative density, plate-thickness, multiple impacts, impact energy and impact angle on the dynamic crushing behavior and energy absorption characteristics were analyzed, showing that the hybrid lattices, due to the existence of larger number of open and closed sub-cells, were able to attenuate the peak impact stress transmitted to the structure and extend the duration of the load pulse (high toughness).
Journal ArticleDOI
Multi-objective optimization for designing a composite sandwich structure under normal and 45° impact loadings
TL;DR: In this paper, a finite element model considering elastic-plastic, damage, and failure behaviors of the composites by using continuum damage mechanics is developed and validated by a normal low-speed impact test.

Explicit algorithms for the nonlinear dynamics of shells
TL;DR: In this article, a finite element formulation and algorithm for the nonlinear analysis of the large deflection, materially nonlinear response of impulsively loaded shells is presented, which can treat about 200 element-time-steps per CPU second on a CYBER 170/730 computer in the explicit time integration mode.

Comparison of the low and high velocity impact response of cfrp
Wesley J. Cantwell,John Morton +1 more
TL;DR: A series of low and high velocity impact tests have been conducted on a wide range of cfrp laminates to examine the initiation and development of damage under these two widely differing loading conditions as mentioned in this paper.
