Abstract The moisture-dependent stress-strain behaviour of European beech wood (Fagus sylvatica L.) has been determined under compression, analytically described for the radial and tangential direction using a modified Ramberg-Osgood approach and realized numerically by a multi-surface plasticity model.

Summary: An integration procedure designed to satisfy plane stress conditions for any constitutive law initially described in 3D and based on classical plasticity theory is presented herein. This method relies on multi-surface plasticity, which allows associating in series various mechanisms.

Abstract The phase field modelling has been extended from brittle fracture to ductile fracture by incorporating plasticity. However, the effects of plastic yield functions and hardening on the fracture behaviour have not been examined systematically to date.

A Multi-Surface Plasticity Method for Lower Bound Shakedown Load
Key Engineering Materials, 2019A new direct method for calculation of lower bound shakedown limits based on Melan’s theorem and a novel, non-smooth multi-surface plasticity model is proposed and implemented in a Finite Element environment. The load history is defined by a finite number of extreme points defining the load-envelope of a periodic load set.

Multi-surface Cyclic Plasticity Sand Model with Lode Angle Effect
Geotechnical and Geological Engineering, 2007A Drucker-Prager J 2 multi-surface-plasticity sand model is modified to employ the Lade-Duncan failure criterion as the yield function. This function includes the first and third stress invariants to account for the dependence of cyclic shear stress–strain behavior on confining pressure and the Lode angle.

An orthotropic multi-surface damage-plasticity FE-formulation for wood: Part I – Constitutive model
Computers and Structures, 2020Abstract Restoration of ancient wooden beams and design of smart wood-based structures are gaining an increasing interest in building industry. In this context, the computational challenge is to develop numerical constitutive models that account for the complex and strongly non-linear behaviour of wood.

Abstract The present study investigates the modelling capabilities offered by the multi-surface damage-plasticity FE-formulation illustrated in Part I [1] when integrated with a regularized extended finite element model. The aim is to tackle discontinuous displacements and interfaces.

A general tangent operator applied to concrete using a multi-surface plasticity model
Computers and Concrete, 2015The present paper aims at developing a method to accommodate multi-surface concrete plasticity from the point of view of a consistency concept applied to general tangent operators. The idea is based on a Taylor series expansion of the actual effective stress at the stress point corresponding to the previous accumulated true stresses plus the current

Non-Smooth Multi-Surface Plasticity
2012Most materials in structures are acted under the complex stress states, i.e., biaxial and multiaxial stresses. Strength theory provides a yield (or failure) criterion, a limiting stress state for elasticity, or an initial deformation for plasticity.
