At microscopic level, natural flaws act as stress concentrators in rock, favoring brittle fracture.
Acoustic emission (AE) monitoring was applied for the qualitative and quantitative …

Several materials of technological interest could be considered as heterogeneous and their
random nature can be accounted to be the cause of the nonlinear behavior. The quantitative …

In the present paper, a novel peridynamic approach is proposed to simulate the fracture
behaviour of quasi-brittle materials. It consists in:(i) an improved bond force-stretch …

The crack propagation simulation is still an open problem in the mechanical simulation field.
In the present work this problem is analyzed using a version of truss-like Discrete Element …

In civil engineering, a quantitative evaluation of damage in materials subjected to stress or
strain states is of great importance due to the critical character of these phenomena, which …

To date, there is no comprehensive approach available that can explicitly model the
complete transient waveforms of acoustic emissions (AE) induced by fracture processes in …

Abstract In the Lattice Discrete Element Method (LDEM), different types of mass are
considered to be lumped at nodal points and linked by means of one-dimensional elements …

In this work, the Acoustic Emission signals were captured by sensors applied to the external
surfaces of a prismatic concrete specimen subjected to compression loads. In this context …

Discontinuous deformation analysis (DDA) computes the mechanical behaviours of discrete
deformable-block systems. It also has been used to simulate continuous rock fracturing, eg …

The lattice discrete element method has been successfully used to simulate the evolution of
damage in structural mechanics. The approach has led to new perspectives in the solution …
