    Impact of a Circular Plate Resting on Sand and Dynamic Response of an Underground Structure. In Computational Techniques for Contact, Impact, Penetration and Perforation of Solids (Vol. , pp. ). (AMD), (AMD). : Leon M Keer. the penetration depth of perforation, perforation hole diamter, shot density or number of shots, and the phasing angle must managed. The perforation interval is the portion of the wellbore reserved for the fluid production by the creation of channels between the wellbore and the reservoir. The perforation controllable parameters are as follows: 2.

    3D hydrocode simulation on the perforation and penetration of reinforced concrete target has been performed. The simulation aims to examine the influence of the following constitutive models for concrete on a projectile's residual velocity: (1) constant-yield strength (2) pressure-dependent yield strength (3) pressure-dependent yield strength+fracturedamage+strain-rate by: computational ballistics iii Download computational ballistics iii or read online books in PDF, EPUB, Tuebl, and Mobi Format.

Computational Impact Mechanics. for contact, impact, and penetration mechanics, based on the Meshless Local Petrov-Galerkin (MLPG) approach. and some ballistic impact and perforation. Penetration events form a class of simulation environments well suited to the solution capabilities of LS-DYNA.

LS-DYNA is unique in offering the analyst the choice of Lagrange, Eulerian (ALE) and Meshfree Methods, and combinations of these methods, for simulating high energy events such as penetration and perforation. In this paper, a new contact-impact procedure called the pinball algorithm is described, for previous studies of contact-impact see [].

A short description of pinball was previously given by Belytschko and Neal[5]. The thrust of the pinball algorithm is to allow vectorization of as much of the slideline calculations as possible.

Summary. Some of the simpler methods in current use for analyzing ballistic impacts by long rod penetrators are reviewed and critiqued. In spite of several obvious shortcomings the eroding rod model has been used as a starting point and guide for an experimental investigation of penetration by:   Abstract: Finite element method (FEM) suffers from a serious mesh distortion problem when used for high velocity impact analyses.
