TL;DR: The results show that this approach can effectively quantify and identify multiple internal flaws without any prior knowledge of their quantity and is more efficient than previously proposed approaches.

TL;DR: In this article, an automatic crack propagation remeshing procedure using the polygon scaled boundary FEM is presented, where only minimal changes are made to the global mesh in each step.

TL;DR: In this paper, a novel sealing device that has a minimal effect on the mechanical behavior of concrete specimens is proposed, which connects one side of silicon plates to a specimen using two specially designed clamps, instead of adhesive and screws the other side of the plates together to a steel plate.

TL;DR: In this article, a scaled boundary finite element method (SBFEM) is used to establish the contact model between the crack faces, where the crack is designated the boundary of the polygonal SBFEM element; the contact tractions on the boundary are assigned to the nodes where the Lagrange multiplier is applied for the point constraints.

TL;DR: In this article, a dynamic contact model for simulating the interaction of two surfaces divided by a dam crack, and a simplified reinforcing steel constitutive model were developed to simulate the effect of earthquake-resistant reinforcement on a cracked dam.
