The development of a quantitative nondestructive evaluation method, as an alternative to visual inspection, for inspecting pre-tensioned bolts in fracture critical bridges is presented. In order to understand the ultrasonic behavior of a wide variety of bolt geometries used in bridges, ... Per saperne di più
Biomechanics of bone has drawn major concern in research due to social and economic demand. In real life, trabecular bone is subjected to multiaxial stresses during routine physiological loading. Fatigue failure of the bone accounts for various clinical implications, thus studies and ... Per saperne di più
The hydro-mechanical (HM) numerical simulation of a shaft seal installed at a fracture zone in a hypothetical host rock using COMSOL is presented. Two different stages are considered in the numerical modelling. Stage 1 simulates the groundwater flow into an open shaft. Stage 2 simulates ... Per saperne di più
In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary ... Per saperne di più
Dr. Tewari is an Associate Professor in the Department of Mechanical Engineering at IIT Bombay. Prior to this he was a staff researcher at the General Motors Global R&D Center, Bangalore. He graduated with a B.Tech degree from IIT Kanpur followed by an MS and Ph.D. from Georgia ... Per saperne di più
This paper describes COMSOL Multiphysics® simulations of the stress and crack development in the area where a masonry wall supports a floor. In these simulations one of the main material properties of calcium silicate, its E-value, was assigned randomly to the finite elements of the ... Per saperne di più
It is well known that the convergence rate of a numerical model is significantly reduced, when the genuine character of the setting with differential equation and boundary condition is not given anymore. Here we examine the decrease of convergence order for models using COMSOL in which ... Per saperne di più
“页岩气革命”使美国成功摆脱了对他国能源的严重依赖，目前我国页岩气的勘探开发也已取得了突破性成果，但是随着页岩气的开发，仍存在三大问题困扰着科学工作者和现场工程师：（1）页岩气开发过程中的渗透率演化规律尚未摸清；（2）在产气过程中，页岩气在产量上往往呈现出不确定性；（3）缺乏针对页岩气进行历史拟合和产量预测的数学工具。针对以上三个主要问题，我们定义非常规储层固有渗透率的演化是裂隙和基质之间物质传输和应力传递的结果，并建立了离散体模型研究孔隙变形与流体流动之间的耦合作用；以此为基础，我们建立双基质双重孔隙介质模型（连续介质模型）研究页岩基质变形与流体流动之间的耦合关系 ...

Introduction:The goal of this simulation is to propose a theoretical model framework based on tracer experiments and equivalent channel models for inversion of unknown parameters of geothermal reservoirs and prediction of thermal breakthroughs in production wells. The problem to be ... Per saperne di più
The prediction of material damage induced by hydrogen transport mechanisms is a major challenge for the development of new steel concepts. Especially the ultra-high strength steel concepts (UHSS), like dual phase and martensitic steels, can exhibit a higher vulnerability to hydrogen ... Per saperne di più
