Through successfully alloying Te at Se sites, material's configurational entropy is obviously increased to optimize phase transition characters and reduce lattice thermal conductivity.
This paper discusses the role of the material or rather configurational force approach in elastic plastic materials with a pre-cracked configuration and gives an overview of some recent numerical investigations of the crack tip field.
The numerical modeling includes a conventional finite element stress analysis and the calculation of the crack driving force based on the concept of configurational (material) forces.
The main goal of this work consists in the elaboration of the material or rather configurational mechanics in the context of multiplicative elastoplasticity.
Therefore, we expect that the here reported findings will lead to follow-on efforts for tuning, doping and tailoring the molecular building blocks of this and related systems, as well as the microstructure of the samples, to obtain barocaloric materials with enhanced configurational, rotational and vibrational entropic effects and optimized caloric performance.
The diffusion of biochemical species (e.g. morphogens, growth factors, migration signals) inside the material is driven by configurational forces, enforced in the balance equations and in the set of constitutive relations.
Furthermore, the study researches the separation of the total dissipation in terms of the change in elastic energy and in terms of the material dissipation by a configurational change obtained from the global energy momentum balance.
A key ingredient is an absolute (fixed) reference configuration, relative to which configurational and deformational changes (rates) with respect to the material (undeformed) and spatial (deformed) configurations, respectively, can be described in a unified fashion.
In this theory, plastic deformation is controlled by an effective temperature that measures the amount of configurational disorder in the material.
To account for this effect, the physical aging of the glassy bridges between the filler particles is captured with two thermal degrees of freedom for the matrix material, namely a kinetic and a configurational one.
