This paper is concerned with a new type of deployable structures that can be rolled up like a tape measure but, unlike a tape measure, are stable in two different configurations. The key to the behaviour of these structures is a particular type of composite construction based on an anti-symmetric lay-up of glass fibres in a polypropylene matrix. The paper presents a finite element analysis usin...

Elastic recovery of the material, called springback, is one of the problems in sheet metal forming of drawpieces, especially with a complex shape. The springback can be influenced by various technological, geometrical, and material parameters. In this paper the results of experimental testing and numerical study are presented. The experiments are conducted on DC04 steel sheets, commonly used in...

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...

Now a days product development using prototype methods for actual usage is a growing concept in engineering. Present work deals with simulation of Compact Tension specimen to get fracture parameters J – integral and Stress intensity factors of product built by polyjet technology 3D printer additive manufacturing system. FEA simulation is carried out with the help of Abaqus software by simulatin...

A computational model of the human head has been developed by Simpleware and the U.S. Naval Research Laboratory (NRL) to simulate head impact. The head model was generated using high-resolution scan data, segmentation and image-based meshing techniques, and has been used in Abaqus for a range of simulations. The NRL/Simpleware head model addresses several key limitations of existing techniques ...

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...

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...

A micromechanics based analysis to predict damage initiation in compressively loaded symmetric notched multiply laminates at efevated temperature under remote biaxial loading is described. The finite element method in conjunction with the commercial code ABAQUS® is used to solve the governing system of equations. The results obtained for the predictions are compared against a set of experimenta...

TION um damage mechanics (CDM) models, particularly when into finite element models, offer the potential for g the damage accumulation process and the risk of eal skeletal structures. For example, Zysset and Curnier ite general inviscid, isotropic damage model to cancellous the central assumption that plastic flow and damage n are intrinsically related [1]. With evidence from our [2] and others...
