Dynamic response of elastic-plastic ideal sandwich beams

Acta Mechanica Sinica, 1992
The dynamic response of elastic-plastic ideal sandwich beams is investigated. The plastic deformation is interpreted as a kind of general loads in the elastic beams, while the moving interfaces between elastic and plastic regions are treated as external restraint conditions.

Elastic-plastic seismic response analyses of structures supporting steam generators

Computers & Structures, 1981
Abstract Three dimensional elastic-plastic seismic response analysis of structures supporting steam generators is carried out. The structural system is idealized as a finite element model composed of elastic beam elements and partially of non-linear spring elements. In the equation of motion the nonlinear restoring force term is divided into a linear

Uncertain dynamic response of a deterministic elastic–plastic beam

International Journal of Impact Engineering, 2003
Abstract The counterintuitive phenomenon of elastic–plastic beam dynamics was demonstrated by Symonds and Yu (ASME J Appl Mech 1985;52:517). An analytical model has been developed to explain this phenomenon from a deterministic viewpoint. However, experimental evidence in (Int J Impact Eng 1991;11(3):341; Int J Impact Eng 1991;11(4):445) showed that ...

Impact Response of Elastic and Elastic-Plastic Sandwich Beams

Earth & Space 2006, 2006
An original model for impact analysis of elastic-plastic sandwich beams is presented, and the effect of sandwich damping is uniquely introduced in the analysis by considering the gradient of beam compliance. By incorporating the compliance (or stiffness) and compliance gradient of the sandwich beams to the equation of motion of the projectile, the ...

Elastic–plastic thermomechanical response of composite co-axial cylinders

Journal of Materials Science, 2006
A new method is developed in this paper to deal with the thermomechanical response of continuous fiber-reinforced composites. Treating the matrix as an elastic-perfectly plastic solid, the analytical formulae of the deformations and stresses of the matrix are obtained from the plasticity theory, axisymmetric equilibrium equation, and stress–strain and ...

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 ...

Dynamic response of elastic-plastic beams with axial constraints

International Journal of Impact Engineering, 1994
Summary Dynamic response of axially restrained beams under transverse impulsive loading is discussed. The material of the beam is elastic-plastic with linear strain-hardening. The ends of the beam are clamped against end rotations and axial displacements. The equations of motion are integrated by the method of finite differences.

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 ...
