Post peak mechanical behavior of Fiber Reinforced Concrete (FRC) under tensile stress states depends not only on the fibers material, shape, content and slenderness but also, on the mechanical and physical properties of the cement paste. Being the improvement of ductility under tension, usually, the main purpose of adding fibers to the concrete composition, an accurate consideration of the...

No Método de Elementos Discretos formados por Barras (Lattice Discrete Element Method – LDEM), o sólido é representado por uma treliça espacial, com massas concentradas nos nós e rigidez definida pela relação constitutiva dos elementos de barra. Tradicionalmente, essa treliça é construída pela repetição de um módulo cúbico, o que exige que a geometria do sólido modelado seja um múltiplo do...

Este trabajo extiende un procedimiento estocástico de modelado de la falla frágil, mediante elementos virtuales (VEs) y elementos de interfaz no lineales (IEs), adaptado a materiales heterogeneos con inclusiones como es el hormigón. Basado en la ergodicidad del refinamiento de mallas poliédricas aleatorias, el enfoque simula la propagación tortuosa de grietas en hormigón con agregados bajo...

In this work, we propose evaluating the constitutive matrix of each element as the average of the nodal constitutive matrices computed at the element's nodes. The nodal constitutive matrix is calculated at each node of the finite element mesh by pre-averaging the strains at the nodes. The resulting stiffness matrix is shown to be convergent. This method achieves a considerable reduction in the...

This study presents an acoustic emission (AE) monitoring strategy based on MEMS (Micro-Electro-Mechanical Systems) sensors applied to 3D-printed structures. AE data were analyzed using the b-value method to track damage development and Natural Time (NT) analysis to identify the onset of critical conditions. A comparison with a commercial piezoelectric sensor revealed similar performance, with...
