The Use of Dijkstra's Algorithm in Assessing the Correctness of Imaging Brittle Damage in Concrete Beams by Means of Ultrasonic Transmission Tomography. [PDF]
The accuracy of transmission ultrasonic tomography for the detection of brittle damage in concrete beams can be effectively supported by the graph theory and, in particular, by Dijkstra’s algorithm.

Concentration versus Oscillation Effects in Brittle Damage [PDF]
AbstractThis work is concerned with an asymptotic analysis, in the sense of Γ‐convergence, of a sequence of variational models of brittle damage in the context of linearized elasticity. The study is performed as the damaged zone concentrates into a set of zero volume and, at the same time and to the same order ε, the stiffness of the damaged material ...

A coupled elastoplastic damage model for brittle rocks
Brittle rock contains an important plastic deformation, which causes microcracks when coupled with stress-induced damage. A new coupled elastoplastic damage model is established in order to discuss the damage behaviors found in brittle rock, based on ...

Description of Brittle Damage in Concrete [PDF]
A simple model of the brittle damage evolution in concrete is presented. The damage evolution is assumed as an isotropic one and the level of damages in material is described by the scalar parameter. The physical equations for this case are formulated.

A peridynamic-informed deep learning model for brittle damage prediction [PDF]
In this study, a novel approach that combines the principles of peridynamic (PD) theory with PINN is presented to predict quasi-static damage and crack propagation in brittle materials.

Graded damage in quasi‐brittle solids [PDF]
AbstractA novel approach to damage modeling for quasi‐brittle solids is presented relying upon a differential inclusion that is closely related to the one of implicit gradient models. The proposed formulation naturally fits in the so‐called nonlocal standard approach, whereby the framework of generalized standard materials is extended to include ...

The mechanical behavior of newly developed composite materials is dependent on several underlying microstructural phenomena. In this research, a periodic 2D geometry of cast X8CrMnNi16-6-6 steel and 10% zirconia composite is virtually constructed by ...

A new quasi-brittle damage model implemented under quasi-static condition using bond-based peridynamics theory for progressive failure [PDF]
A novel quasi-brittle damage model implemented under quasistatic loading condition using bond-based peridynamics theory for progressive failure is proposed to better predict damage initiation and propagation in solid materials.

Three regularization concepts are assessed regarding their variational structure and interference with the predicted physics of (quasi-)brittle damage: the fracture energy concept, viscous regularization and micromorphic regularization.
