Uncertainty in COMSOL Multiphysics® software simulations due to (a) model parameter uncertainties and (b) mesh-induced truncation errors, is estimated using a design-of-experiments approach [1, 2, 3], and a nonlinear least squares logistics fit method [4, 5], respectively. Examples to ... 詳細を見る
In this paper we made an attempt to maximize the power output in the different piezoelectric materials in a unimorph cantilever beam configuration. In this research, a macro scale unimorph piezoelectric power generator prototypes consists of an active piezoelectric layer, stainless steel ... 詳細を見る
The novel Micro Electro Mechanical System (MEMS) based Piezoresistive stain sensor is presented in this paper. The main goal of this sensor is to monitor the localized strain in the highway bridges especially near the crack tips. Monitoring the crack growth on the bridges can lead to ... 詳細を見る
A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. 詳細を見る
The two wooden cabinets of Jan van Mekeren that are located in Amerongen Castle show comparable wood damage; in particular large cracks in the cabinet doors are clearly noticeable. It is assumed that these cracks were caused by bad indoor climate conditions in the castle. Combined ... 詳細を見る
The acoustoelastic effect relates the change in the speed of an acoustic wave travelling in a solid, to the pre-stress of the propagation medium. In this work the possibility of assessing nondestructively the stress status in metal sheets, by using the acoustoelastic effect, is ... 詳細を見る
A problem of damage prediction in aircraft structure and its non-destructive evaluation is very important for aircraft structural health assessment. The analysis of the features of direct impact of thin-walled laminate component of aircraft was performed by COMSOL Multiphysics software. ... 詳細を見る
We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate. 詳細を見る
The safety of large civil structures is often evaluated by means of numerical models based on the Finite Element Method (FEM). In the last year, the elastic behavior of the Microplane Model was implemented in COMSOL because it is a promising approach able to overcome the limit typical of ... 詳細を見る
The design of a magnetic resonance imaging (MRI) RF coil using finite element method-based analysis is an essential part of a multi-year research project at the National Institute of Standards and Technology, Gaithersburg, Maryland, where the goal of the project is to develop a “phantom” ... 詳細を見る
