When analyzing a failure or crack propagation problem by FEM, there are the following challenges to solve. (1)It’s necessary to make element boundary match to the failure surface or the crack surface. (2)The failure shape and the ...

In this paper, the ballistic impact test is described in which fragment simulating projectiles (FSPs) have been used against thick plates made of an aluminum alloy. To perforate the plates, the projectiles must have reached velocities ...

The purpose of this research is to develop a fully-tabulated, anisotropic, asymmetric and rate dependent material model for solid elements. Physical tests of several metallic materials have shown to have anisotropic (or orthotropic) ...

Accurately and efficiently simulating strongly coupled fluid structure interactions has been a challenge. In this presented study, the interaction of a lab-scale experiment using an automotive roof panel with an air flow applied ...

The use of software for the simulation of airflow around ground vehicles plays an important role in the design of a vehicle. Traditionally companies within the automotive industry sector have a Computational Fluid Dynamics department ...

The 64 km/h frontal offset test is run with a deformable barrier, and the first numerical model of this barrier was made with solid elements to represent the honeycomb blocks. However this required development of a special element ...

The escalating usage of Advanced High Strength and Press Hardened Steels to enhance crashworthiness while improving fuel efficiency through light-weighting of vehicles, has become a surmountable challenge to the auto industry. ...

Woven lattice materials were modelled to develop thin sheet dampers for attenuation of vibrations in high temperature environments. 3-D weaving has enabled manufacturing of woven lattice materials from metallic fibers that are ...

Understanding the interaction between a projectile and a ballistic protection structure is the first requirement for the design and optimization of an effective protection. Since the impact phenomenon involves highly dynamic and ...

It is necessary to restrict the damage area for the enhancement of ship survivability under the internal blast of a Semi-Armor Piecing (SAP) warhead inside a ship’s compartment, and to develop design guidance and performance ...
