Influence of yield-surface shape in simulation of ballistic impact [PDF]
International Journal of Impact Engineering, 2017 Abstract A high-exponent yield criterion is applied in 3D nonlinear finite element simulations of ballistic impact. The computational models are based on a comprehensive experimental study including material tests of 12 mm thick high-strength Weldox 700 E steel plates and ballistic tests where the plates were struck by blunt-nosed and ogive-nosed ...

Ballistic Impact Simulation of Ceramic/Metal Armor Structures
Uluslararası Muhendislik Arastirma ve Gelistirme Dergisi, 2017 The study presents a comparative numerical investigation on ballistic performance of ceramic/metal armor structures. 2D axisymmetric numerical model was developed for ballistic impact simulations using LS-DYNA ® finite element software. The armor structures included combinations of boron carbide (B 4 C), Al6061-T6 and 4340 steel constituents.

FRICTION MODELING IN SIMULATING BALLISTIC IMPACT. A REVIEW
Proceedings on Engineering Sciences, 2019 This paper presents a review on using friction coefficient in modelling ballistic impact. The are discussed on friction introduced in modelling the impact at different levels: micro (fiber and yarns), meso (woven or unidirectional fabrics) and macro (layered or equivalent monoblock structures).
