Numerical analysis of highly deformable elastoplastic beams
Latin American Journal of Solids and StructuresThe objective of the present study is to develop a numerical formulation to predict the behavior of highly deformable elastoplastic thin beams. Following the Euler-Bernoulli bending, the axial and shear effects are neglected, and the nonlinear second ...

Discontinuities in regularised media [PDF]
, 2011 Discontinuous interpolation of the problem fields in non-local and rate-dependent media is considered. The necessity of discontinuities in the analysis of failure processes and some of the requirements for the introduction of discontinuities in ...

Elastoplastic modeling of fatigue cracks
Омский научный вестникThe presented work provides a detailed analysis of modern approaches to creating elastoplastic models of surface crack growth that take into account the influence of the type of biaxial loading on the development of stresses and strains at the crack tip ...

Elastoplastic Behavior Identification for Heterogeneous Loadings and Materials [PDF]
Experimental Mechanics, 2007 Image processing techniques provide access to full field measurements of different thermomechanical data (strain; strain-rate; temperature ...). These techniques have become increasingly useful for obtaining fine and local descriptions of material properties.

Hysteretic behavior modeling of elastoplastic materials [PDF]
Theoretical and Applied Mechanics, 2008 In the present paper the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular cross section and cyclic bending
