Impact damage in brittle materials in the elastic-plastic response régime

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1978
Abstract The impact fracture created in the elastic-plastic response régime has been characterized in terms of its surface extension and penetration. A numerical dynamic analysis has been performed of a typical impact within this régime to indicate some of the principal characteristics of the contact behaviour and the stress field ...

A Method for Determining the Elastic-Plastic Response Ahead of a Notch Tip

Journal of Engineering Materials and Technology, 1999
The stress distribution ahead of a notch tip is the prerequisite to calculating the driving force for cracks emanating from notches. This article first examines whether two commonly used engineering methods, which are often employed to determine the response at a notch tip, can be applied to evaluate the elastic-plastic response ahead of a notch tip ...

Dynamic response of elastic-plastic pin-ended beams by galerkin's method

International Journal of Solids and Structures, 1994
Abstract The problem of the elastic-plastic response of beams with pinned ends under short pulse loading is solved by Galerkin's method (with six degrees of freedom). Numerical results are compared with results obtained by the ABACUS program. An approximate “elastic recovery” type solution is proposed.

Elastic-plastic response of a sandwich cylinder subjected to internal pressure

Journal of Strain Analysis, 1971
The propagation of plastic zones in a thin-walled sandwich-type cylinder has been analysed theoretically. Boundary conditions are clamped-clamped at both ends, i.e. no rotation is permitted. The material was assumed to behave isotropically and to obey the yieid criterion of Huber-Hencky-von Mises.

Magnetomechanical Instabilities in Elastic-Plastic Cylinders, Part II: Plastic Response

Journal of Applied Mechanics, 1996
The analysis of elastic instabilities in metal cylinders when subjected to electromagnetic fields (Littlefield, 1996a) is extended in this work to include elastic-plastic flow. The cylinder is assumed to be infinitely long and perfectly conducting. The Prandtl-Reuss elastic-plastic material model is the assumed constitutive law, with the von Mises ...

The elastic–plastic indentation response of a columnar thermal barrier coating

Wear, 2010
Thermal barrier coatings with a columnar microstructure are prone to erosion damage by a mechanism of surface cracking upon impact by small foreign particles. In order to explore this erosion mechanism, the elastic indentation and the elastic-plastic indentation responses of a columnar thermal barrier coating to a spherical indenter were determined by ...

Elastic-Plastic Response of Solids Under Shock-Wave Loading

2004
Because shock-wave and high-strain-rate phenomena are involved in a broad range of technological applications, we are interested in understanding time-dependent mechanical properties of materials subjected to these extreme loading conditions. The shock-wave technique also provides a powerful tool for scientific investigation of material properties at ...
