Abstract: This paper presents an energy-based approach for the finite-element modeling of mixed-mode cohesive crack propagation. This approach predicts the propagation of a quasistatic cohesive crack based on the principle of energy ...

Abstract: Using a mixed‐mode extension of the Hillerborg fictitious crack model, a practical interface finite element approach is used to model discrete crack propagation. The fictitious crack tip propagates perpendicular to the ...

Abstract: Based on an energy principle and a virtual crack extension technique, a practical finite-element modeling approach for the automatic mixed-mode two-dimensional (2D) linear elastic fracture mechanics (LEFM) crack-propagation ...

Abstract: The central challenge in developing deterioration models for infrastructure facilities based on field data, is the right selection of base models along with the specific nature of the available condition data. A parametric ...

Abstract: Impact tests using a soft gelatin projectile were performed to identify failure modes that occur at high strain energy density during impact loading. Failure modes were identified for aluminum plates and for composites ...
