Two-Dimensional Mesoscale Finite Element Modeling of Concrete Damage and Failure

3D Mesoscale Finite Element Modelling of Concrete

Concrete is non-homogeneous and is composed of three main constituent phases from a mesoscopic viewpoint, namely aggregates, mortar matrix, and interface transition zone (ITZ). A mesoscale model with explicit representation of the three distinctive phases is needed for investigation into the damage processes underlying the macroscopic behaviour of the composite material. This paper presents a f...

Finite Element Modeling of Reinforced Concrete Beams Exposed to Fire

Abstract: The practical implementation of performance-based fire safety design of reinforced concrete (RC) structures hinges on the availability of accurate numerical simulation tools for the behavior of RC members exposed to fire. This paper presents a three-dimensional (3D) finite element (FE) model for the accurate prediction of both the thermal and the mechanical behavior of RC beams expose...

A two dimensional Simulation of crack propagation using Adaptive Finite Element Analysis

Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...

A Multigrid Finite Element Method for the Mesoscale Analysis of Concrete

In classical engineering models concrete structures are described by homogenized values of material properties such as elastic modulus and ultimate stresses. However, as concrete mainly consists of natural aggregates and mortar matrix, it is a heterogeneous material with significant physical differences among its components. For most realistic simulation, we propose to process a mechanical anal...
