This paper is concerned with the numerical simulation of hot metal forming, especially superplastic forming. A complete thermo-viscoplastic formulation at finite strains is derived and a unified stress update algorithms for thermo-elastoplastic and thermo-elastoviscoplastic constitutive equations is obtained. The resulting unified implicit algorithm is both efficient and very inexpensive. Finally, numerical simulations of superplastic forming are exposed. [less ▲]

The formulation of macroscopic constitutive laws for the behaviour of masonry is a complex task, due to its strongly heterogeneous microstructure which influences its overall mechanical behaviour. This has triggered in the past decade the formulation of homogenisation methods, both for linear and damaging behaviours, and for in and out-of-plane loading conditions. This contribution deals with two-scale computational framework, in which the material behaviour of a structural masonry shell is sampled by resorting to computational homogenisation applied on a microstructural description of masonry constituents. The structural damaging behaviour is modelled by incorporating localising hinges in a coarse scale thin shell description. The appearance, the orientation and the softening mechanical response of these hinges are directly deduced from the computational homogenisation scheme. This procedure allows incorporating naturally the anisotropic damaging effects of the masonry material degradation. The contribution will illustrate the two-scale results by comparing them to full fine scale models. [less ▲]

This paper presents a multi-scale framework for the failure of periodic quasi-brittle thin planar shells. The failure behavior of textured or periodic heterogeneous materials is strongly influenced by their mesostructure. Their periodicity and the quasi-brittle nature of their constituents result in complex behaviors such as damage-induced anisotropy properties with localization of damage, which are difficult to model by means of macroscopic closed-form constitutive laws. A computational homogenization procedure is used for the in-plane and out-of-plane behavior of such planar shells, and is combined with an acoustic tensor-based failure detection adapted to shell kinematics to detect the structural-scale failure. Based on an assumption of single period failure, the localization of damage at the structural scale is represented by means of mesostructurally informed embedded strong discontinuities incorporated in the macroscopic shell description. A new enhanced scale transition is outlined for shell failure, based on an approximate energy consistency argument to objectively upscale the energy dissipation. The corresponding multi-scale framework results are compared with direct fine-scale modeling results used as a reference for the case of masonry, showing good agreement in terms of the load-bearing capacity, of failure mechanisms and of associated energy dissipation. © 2010 John Wiley & Sons, Ltd.
