This paper presents the simulation of the tensile modulus and the tensile strength of shor t glass fibre reinforced Polypropylene. Various formulae of the shear-lag theory were implemented in an analytical calculation program to evaluate the tensile strength values. Based on the homogenization approach the modulus values and the strength values, applying an existing failure criterion, were calc...

The main purpose of bumper is to absorb shock in case of a collision. Several materials have been used to develop these shock-absorbing capabilities, such as steel, aluminium, glass mat thermoplastics and sheet molding compound. The purpose of this project is to design a bumper which is to improve crashworthiness of the bumper beam. Crashworthiness is the ability of the bumper beam to prevent o...

We study the static as well as the glassy or dynamical transition in the meanfield p-state Potts glass. By numerical solution of the saddle point equations we investigate the static and the dynamical transition for all values of p in the nonperturbative regime p > 4. The static and dynamical Edwards-Anderson parameter increase with p logarithmically. This makes the glassy transition temperature...

We have succeeded to develop a technique enabling molecular level composite treatment by utilizing electrical characteristic (ion) of the materials to form 3D micro-structure, and it can bind three-dimensionally and selectively cross points of continuous (fibriform) object of nanometer size with high-speed and low cost. Application fields of the proposed technique may be fiber process, composit...

The use of metallic materials in automotive industry leads to increasing fuel consumption and cost, so trends are starting lighter cheaper materials. In applications, fibers used composites because they stronger, stiffer, than bulk materials, can achieve higher energy absorbing compared purpose this work is study the potential utilization natural crash applications. experimental procedures (the...

Biomineralized ferric oxide microbial mats are ubiquitous features on Earth, are common in hot springs of Yellowstone National Park (YNP, WY, USA), and form due to direct interaction between microbial and physicochemical processes. The overall goal of this study was to determine the contribution of different community members to the assembly and succession of acidic high-temperature Fe(III)-oxi...
