The main objective of the present work is to perform stress analysis on composite laminates under unaxial/biaxial loading to serve as a preliminary data for test verification. A detailed calculation based on the Classical Lamination Theory was performed for a laminate. The material used was carbon/epoxy applying a pure uniaxial load followed by a biaxial load. It was observed that the failure ...

Two friction stir welding models are presented – a global thermal model using the temperature dependent heat source and a local material flow and heat generation model allowing for detailed investigation of different contact conditions. The two models are coupled into a larger local-global model. The flow model includes frictional dissipation from the contact between the work piece and the ...

Reduction of the engine vibration and the dynamic forces transmitting from engine to the automotive body structure has always been an important part of automotive research. Automobile engineers face the task of creating a mechanism to absorb these vibrations and provide a smooth ride. The usage of Motor Mounts is the best solution for dampening the effects of vibrations and oscillations. This ...

Vibration and Dynamic performances of the rotating machinery are conventionally evaluated based on the dominant structural forces such as the centrifugal forces. The increase in rotational speed, miniaturization and performance, demands for improved and accurate evaluation of the vibration performance. The inclusion of coupled effects of fluid and centrifugal forces can contribute significantly ...

This paper presents a novel design of multi-disks Magnetorheological braking system (MR brake) for automotive application. Magnetic saturation in both electromagnetic core and MR fluid is considered in this paper. The electromagnetic analysis of the proposed configuration is carried out using Finite Element based COMSOL Multiphysics® software (AC/DC Module). The system geometry, created using ...
Scale-up Design of Ultrasound Irradiator for Advanced Oxidation Process (AOP) Using COMSOL Multiphysics® Simulation
The Ohio State University, Columbus, OH, USA
Ultrasound is a promising green technology for the advanced oxidation process (AOP) since it adds no chemicals to the treated water. In this paper, COMSOL Multiphysics® was used as a tool to design and characterize an ultrasound irradiator with multi-stepped configuration, which aims to overcome disadvantages of typical irradiators and to enhance contaminant removal in large-scale water ...

COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin alloy strain gages were installed at the four high-strain regions of the spring element. The four gages were ...
