Critical state models in computational geomechanics
A. Gens, D.M. PottsElasto‐plastic models based on critical state formulations have been successful in describing many of the most important features of the mechanical behaviour of soils. This review…
Contact analysis of large numbers of interacting bodies using discrete modal methods for simulating material failure on the microscopic scale
John R. WilliamsThere has been interest recently in analysing soil, ceramic powders and other materials on the microscopic level so that macroscopic phenomena, such as failure, can be related to…
A material law for coupled local yielding and geometric instability
B. Kröplin, D. DinklerThe load carrying capacity of steel structures, built of slender members like bridge cross‐sections, depends on coupled yielding and buckling of the stringers and the plate strips…
Integration along the path of loading in elastic‐plastic problems
J.B. Martin, W.W. BirdThis paper considers the classical problem of the deformation of an elastic‐plastic body subjected to a prescribed history of loading. Attention is focused on the basis for the…
Yield surfaces for perforated plates
M. KönigA method is presented by which elastoplastic constitutive relations for the solid material equivalent to a perforated plate can be obtained, by performing numerical experiments…
Dynamic elastic‐plastic behaviour of a frame
Stefan Messmer, Mahir SayirThe full time response of a space frame under impact loading perpendicular to the frame plane is discussed. Theoretical solutions and experimental results are presented and…
Effects of non‐proportional loadings in cyclic elasto‐viscoplasticity: experimental, theoretical and numerical aspects
A. Benallal, D. MarquisAn elasto‐viscoplastic constitutive model valid under general complex cyclic loadings is proposed to describe the multiaxial behaviour of engineering metallic materials. Its…
Viscoelastic finite element analysis in design of potash mines
Y.S. Yu, C.G. Ong, P. MottahedComputer simulation is playing an increasingly important role in evaluating the short and long term structural stability of underground mine openings, and in ground control…
Exact closed‐form solution of the return mapping algorithm in plane stress elasto‐viscoplasticity
J.C. Simo, S. GovindjeeIn Simo and Taylor, the classical radial return algorithm of Wilkins and Krieg and Key for plane strain and three‐dimensional J2‐flow theory, is extended to the case of plane…
