Interaction of nonlinear waves in materials with elastoplastic behavior

Journal of Applied Mechanics and Technical Physics, 1994
In the article under review, a factorization is provided for the system of equations for a nonlinear Maxwell body which is universal for describing the dynamic behavior of condensed materials with elastoplastic kinetics. A rough system of independent nonlinear equations is obtained for waves related to various families of longitudinal characteristics ...

Anisotropic Elastoplastic Material Behavior in Fabric Structures

2003
Many composites consist of a fabric structure embedded in a matrix material. The fibres are often made of material which shows noticeable plastic deformation. The overall stiffness of the specimens is usually determined by the stiffness of these fibres, such that the correct modeling of the orthotropy of the composite is very important.

Elastoplastic Damage Behavior of a Mortar Subjected to Compression and Desiccation

Journal of Engineering Mechanics, 2007
This paper deals with experimental investigation and numerical modeling of drying effects on the mechanical behavior of cement-based materials. First, the main results from an experimental study on the mechanical behavior (failure strength, induced damage, and plastic deformation) of a mortar subjected to the desiccation process are presented.

Micromechanical Modeling and Simulation of the Elastoplastic Behavior of Composite Materials

2020
Composite materials are the preeminent drivers for the significant enhancement to products that meet recent industrial requests. Nevertheless, their variability and the complexity of the innovative products introduce a great challenge in predicting the mechanical response fundamental for the composite design engineering.

Topology and shape optimization including elastoplastic material behavior

7th AIAA/USAF/NASA/ISSMO Symposium on Multidisciplinary Analysis and Optimization, 1998
In order to generate a reliable design the nonlinear structural response, e.g. buckling or plasticity, has to be considered in topology and shape optimization. In the present study material topology optimization determining the basic layout is extended to elastoplasticity.

Elastoplastic analysis of the nonlinear stage of behavior of a soil base

Soil Mechanics and Foundation Engineering, 1991
1. In an elastoplastic calculation of a base, it is expedient to use the Coulomb—Mohr criterion as the condition of plastic flow for upward yielding zones and the Tresca—Hill criterion for the core under the plate and deep zone.

ELASTOPLASTIC CONSTITUTIVE MODEL AND MECHANICAL BEHAVIOR OF UNSATURATED LOESS

Composites: Mechanics, Computations, Applications: An International Journal
To address the issue of the absence of a suitable loess constitutive model in the study of seismic response in loess tunnels, the elastoplastic constitutive model of unsaturated loess was established by replacing the fixed yield surface with the yield surface (i.e., the variable loading surface).

Effect of Some Parameters on the Elastoplastic Behavior of Green Sand

2004
The behavior of the casting sands at high temperatures (up to 600°C) is experimentally presented. Based on a parametric study, the predictions are well discussed and compared with the experimental results. Triaxial compression tests at different temperatures (20 to 600 °C) were performed in foundry sand (Ami Saada et al., 1996, Ami Saada 1997, Ami ...
