Early Detection of Damages Based on Comprehensive Theory of Deformation and Fracture [PDF]
The 18th International Conference on Experimental Mechanics, 2018 Numerical studies have been conducted based on the recently published Deformation Field Theory. Effects of pulling rates on displacement waves and volume expansion waves are analyzed in a finite element model (FEM) of a solid experiencing a uni-axial tensile load.

Materials Theory, 2017 Cracks are created by massive breakage of molecular or atomic bonds. The latter, in its turn, leads to the highly localized loss of material, which is the reason why even closed cracks are visible by a naked eye.

A mesoscopic theory of damage and fracture in heterogeneous materials
Theoretical and Applied Fracture Mechanics, 2004 Abstract Deformation patterns in solids are often characterized by self-similarity at the mesolevel. The framework for the mechanics of heterogeneous solids, deformable over fractal subsets, is briefly outlined. Mechanical quantities with noninteger physical dimensions are considered, i.e., the fractal stress [σ ∗ ] and the fractal strain
