Beam theories are well-developed for slender structures with homogeneous materials and isotropic cross-sections. The traditional beam theories do no apply to beams made of different materials in the cross-section. Therefore, a homogenization-based numerical model is needed to compute ... En savoir plus
The homogenized material properties of a composite are computed based on the temperature-dependent properties of matrix and fiber. The homogenized parameters are compared to the analytical values derived from the rule of mixtures. This is an extension of model https://www.comsol.com ... En savoir plus
This is a demo model to show how to model connections in a mechanical system using Multibody Dynamics interface. In this model, pantograph mechanism is modeled. The purpose of this mechanism is to produce an identical, either enlarged or miniaturized, copy of an existing drawing. En savoir plus
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... En savoir plus
Solving very large pressure acoustics models in the frequency domain can be challenging. Several iterative solver suggestions exist for the default physics setups and the default quadratic Lagrange discretization. For very large models it can be advantageous to switch from quadratic to ... En savoir plus
In direct bonding, particulate contamination at the interface can significantly reduce bonding quality. Even micron-scale particles may prevent local contact and lead to large interfacial voids. This model demonstrates a 3D simulation workflow for die-to-wafer (D2W) direct bonding. The ... En savoir plus
A simple way to estimate the value of π is by using a pendulum, whose oscillation period can be measured and used to calculate an approximation. This simulation app is based on a model that uses the <em>Multibody Dynamics</em> interface to describe the motion of a simple ... En savoir plus
This model describes the corrosion of magnesium (Mg) alloys in physiological environments using a phase-field formulation. The approach couples Mg dissolution kinetics with ionic transport, enabling the transition from activation-controlled to diffusion-controlled regimes to be captured. ... En savoir plus
This model analyzes the uncertainty in focused ultrasound induced tissue heating. The material properties for the tissue mimicking material, including the uncertainty, are taken from the FDA Medical Device Development Tool: Tissue Mimicking Material (TMM) for Preclinical Acoustic ...
