Modern approaches to plasticity : proceedings of a workshop held in Horton, Greece, 12-16 June 1992 under the patronage of the Council of Europe /

Constitutive modelling of granulate materials has achieved significant progress in recent times although some challenging problems still remain to be solved. Many of the 35 contributions in this volume are devoted to modelling but there are also papers investigating the phenomena to be modelled. For...
