Several failure criteriaAuthor: Armin Yousefi Kanani. This paper presents a ballistic impact simulation of an armor-piercing projectile in hybrid ceramic/fiber reinforced composite armor. The armor is composed by an alumina plate and an ultra high molecular weight polyethylene composite. Three different constitutive models (ceramic, composite and adhesive) were formulated and implemented into.

To address this goal, an assessment of current analytical tools for impact analysis was performed. Assessment of the analytical tools for impact and penetration simulations with regard to accuracy, modeling, and damage modeling was considered as well as robustness, efficient, and usage in a wing design : Norman F.

In the applications of composite honeycomb sandwich structures, they often are severely impacted, resulting in partial penetration or complete perforation.

To study the mechanical response of composite honeycomb sandwich structures under high-velocity impact, an extended P - α model was developed to describe the equivalent property of. Penetration process of bullet core and the mechanism of composite target plate were analyzed, difference of anti-bullet properties between the two target structures A, B were compared, the influence different points of impact have on resistance of ceramic composite target plate were studied.

CISM International Centre for Mechanical Sciences, vol Cited by: In this study, perforation performance tests of multi layered ceramic-metal composite armours consisting of alumina ceramics (% Al2O3) and aluminium Al T back-up materials against a mm armour piercing (AP) bullet and a mm AP bullet impact were numerically simulated and then these simulations were verified by the ballistic by: 3.

Ballistic Materials and Penetration Mechanics deals with ballistically protective materials and penetration mechanics. The book discusses historical and practical considerations of ballistic protection, including metallic armor, as well as ballistic testing methodology, the ability of a protective material to stop or slow down a particular projectile, and the theoretical aspects of penetration Edition: 1.

A wealth of knowledge has been published on dynamic impact response of composite materials and structures. Yet, with continually emerging materials and processes, there is a lack of systematic structure-property-performance relationships that provide guidelines on dynamic impact Cited by: Design and Analysis Workflows for Advanced Simulation of Composite Structures K Indermuehle, A Prior Dassault Systèmes Simulia Valley Street, Providence, RI - USA [email protected], @ SUMMARY This paper reviews the processes, methods and tools required to carry out advancedFile Size: 5MB.

Composites damage and failure models. Impact damage in composite laminates usually is a combination of several damage modes. The typical failure mechanisms are fibre breakage, matrix cracking, fibre/matrix debonding and delamination at the ply interfaces (Liu, ).Cited by: 2.

For the impact and penetration simulations, the pre-processing step requires more preparation than other analyses because of the need to develop appropriate finite element models for contact, failure, and penetration.

The INGRID computer code has been used in the present study for this step. The analysis step involves the nonlinear transient dynamic response prediction for the dynamic behavior prior to impact, the nonlinear impact/penetration Cited by: As a result, extensive crushing simulations for composite structures had been conducted and reported in the open literature.

In this paper, it distinguished the state of the art in composite. Volume 2 offers research on impact and penetration data from projectile effects on surfaces ranging from natural phenomena such as water, to metallic plating and material-engineered armors.

Recent advances in reactive fragments, which provide enhanced terminal effects, are presented. Individual plies are the basic building blocks in the computational mesomechanics of laminates. A virtual laminate is thus built with plies made up of different unidirectional or woven fibres (carbon, glass, aramid, etc.) embedded in a matrix (normally an epoxy resin) according to a predefined stacking sequence, as shown in Figure The ply interfaces are also explicitly included in the by: 5.

Impact loads from projectile penetration and impact are considered in this study in an effort to numerically replicate experimental data.
