Shear instabilities in the form of shear bands are often observed during high speed, plastic deformations of metals. According to one theory, their formation is attributed to eeective strain-softening response, which results, at high strain rates, as the net outcome of the innuence of thermal softening on the, normally, strain-hardening response of metals. In order to test the core instability ...

The objective of the paper is modeling of material softening after the deformation. The main problem of almost every model with digital material representation is consideration of recrystallization as the only mechanism of material softening. Static recovery is introduced into the model based on frontal cellular automata. An influence of static recovery on softening process is twofold. Static r...

Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum concept has emerged as an effective means for regularizing the boundary value problems with strain softening, capturing the size effects and avoiding spurious localization that gives rise to pathological me...

This paper describes a new framework for relational graph matching. The starting point is a recently reported Bayesian consistency measure which gauges structural differences using Hamming distance. The main contributions of the work are threefold. Firstly, we demonstrate how the discrete components of the cost function can be softened. The second contribution is to show how the softened cost f...

Introduction Conclusions References

to softening or breaking down of the brain-substance. In some of the cases I recorded and which terminated favourably, it is, of course, to be assumed that the congestions or other changes were of a transient and curable character. In the present paper I propose to consider the cases which may be regarded as inflammatory in their nature, but which, though exceedingly dangerous, are amenable to ...
