Material-technological Modelling of C45 Steel Die Forgings

open access: yesProcedia Engineering, 2015
AbstractMaterial-technological modelling is based on thermo-mechanical treatment of a small amount of real material using a thermomechanical simulator. This is a procedure allowing quick and accurate changes to selected parameters of the thermomechanical treatment.

Irreducible matrix resolution of the elasticity tensor for symmetry systems

open access: yes, 2018
In linear elasticity, a fourth order elasticity (stiffness) tensor of 21 independent components completely describes deformation properties of a material. Due to Voigt, this tensor is conventionally represented by a $6\times 6$ symmetric matrix.
