On the elastic–plastic response of hemitropic Cosserat solids

Mathematics and Mechanics of Solids
A model for the elastic–plastic response of solids is formulated on the basis of the concept of a materially uniform Cosserat continuum. Plastic deformation and rotation tensors are defined in terms of invertible mappings of a local archetypal state, encoding the constitutive response of the material, to a neighborhood of a material point in an ...

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 response of a circular hole to repeated loading

International Journal for Numerical and Analytical Methods in Geomechanics, 1989
AbstractA closed‐form analysis for elastic—plastic response of a circular hole in an infinite Mohr—Coulomb medium under axisymmetric loading shows the effect of repeated loading on the stress and displacement fields around the hole. Examples show how repeat‐load closure increment is affected by working load, internal pressure, material compressive ...

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

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.

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 ...

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 ...

Elastic-Plastic Dynamic Response and Buckling of Laminated Thin Shells

Journal of Composite Materials, 1991
A 48 degree-of-freedom doubly-curved quadrilateral laminated thin shell element including the effect of anisotropic plasticity is formulated to study the static, dynamic response and buckling of thin shell structures. The effect of geometric nonlinearity is also included.

The Anomalous Response of an Elastic-Plastic Structural Model to Impulsive Loading

Journal of Applied Mechanics, 1989
To simulate the response of a pin-ended elastic-plastic beam, a nonlinear structural model, i.e., a double-tier-spring model is analyzed to follow its deformation process after it is subjected to impulsive loading. After examining the first integral of the equation of motion, in the final elastic vibration, combined with other conditions, a region in ...
