This paper presents the results of an analytical investigation conducted to replicate experimentally obtained behavior, and better understand the behavior of the proposed structural fuse concept for bridges that is presented in a companion paper. First, a steel plate shear link (SPSL) proposed as a new type of structural fuse is described. Equations are derived to define its shear-moment intera...
A finite element (FE) model of the human foot and ankle was developed from 3D reconstruction of 2 mm coronal MR images from the right foot of a normal male subject using the segmentation software, Mimics. Solid models of 28 foot bones and encapsulated soft tissue structures models established in Solidworks software were imported into ABAQUS for creating the tetrahedral FE meshes. The plantar fa...
The main purpose of this work is the computational simulation of the sensitivity coefficients of the homogenized tensor for a polymer filled with rubber particles with respect to the material parameters of the constituents. The Representative Volume Element (RVE) of this composite contains a single spherical particle, and the composite components are treated as homogeneous isotropic media, resu...
Multi-site damage (MSD) has been a challenge to aircraft, civil and power plant structures. In real life components are subjected to cracking at many vulnerable locations such as the bolt holes. However, we do not consider for the presence of multiple cracks. Unlike components with a single crack, these components are difficult to predict. When two cracks approach one another, their stress fiel...
The present work describes a multiscale methodology which has been developed for modeling of impact damage in the laminated composite structures. The methodology employs the High Fidelity Generalized Method of Cells (HFGMC) micromechanical model for the prediction of the local stress and strain fields, within the representative unit cell of the unidirectional composite material. The Mixed Mode ...
The aim of this paper is to carry out extensive numerical investigations about the effect of various parameters on both buckling loads and ultimate behavior of continuous partially composite castellated beams under vertical loads. Efficient nonlinear 3D Finite Element Model using ABAQUS software is developed. The initial geometric imperfection and material nonlinearities were carefully consider...
The Virtual Race Track, VRT, suite of simulations is the most recent addition to the automation tools known as Virtual Package Simulation, VPS, for analyzing the performance of plastic bottles. These new simulations predict the dynamic performance of bottles traveling on conveyors. The objective is to determine if the bottles remain standing after impacting fixed guide rails and gates. The bott...
Abstract: This paper builds upon previous studies (Farrugia, 2006, 2008) for developing a more physical approach to predict the mechanisms of high temperature ductile damage acting at surface/sub-surface and across the length scale of continuously cast free cutting steel billet feedstock. A methodology combining mechanical testing and modelling has been developed to account for local microstruc...
The term ‘Unconventional Reservoirs’ is used in the oil and gas industry for hydrocarbon reservoirs that have very low permeability in the magnitude of microdarcy (μd) and therefore rely on artificially introducing pathways for fluids and gases, commonly by using hydraulic fracturing techniques, to enable economic production. This approach of using fracturing stimulation campaigns is also incre...
