La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
Isotropic compression is a common material test in soil mechanics. The modified Cam-Clay (MCC) model describes the relation between the void ratio and the logarithm of the pressure. In this example, a cylindrical soil sample under isotropic compression is simulated. It is verified that, ... Per saperne di più
In this example, triaxial and oedometer tests are simulated using the Modified Cam-Clay material model. A nonlinear stress-strain relation is recovered with the constant Poisson's ratio formulation. The hardening and softening behavior is recovered for normally consolidated and highly ... Per saperne di più
The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... Per saperne di più
The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure. In this model, a vertical displacement and a confinement pressure are applied on the sample ... Per saperne di più
This model shows how to set up a uniaxial compression test on a prestressed soil sample. Due to uniaxial compression and simple initial stress values, it is possible to determine the vertical yield stress analytically. The soil sample is modeled with soil plasticity and the Mohr–Coulomb ... Per saperne di più
Roll forming processes are widely used in metal processing, battery electrode production and manufacturing processes. The model demonstrates the process of roll forming, where a workpiece is pressed after passing through a pair of rollers. The workpiece is carried between rollers by ... Per saperne di più
The katana is a legendary Japanese sword used by the samurai in olden days. Here, we present a simple model where we simulate a differential hardening process to explore some of the features of the katana.

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. ... Per saperne di più
This model showcases a nail penetration experiment into a layered battery. It couples the Solid Mechanics, Lithium-Ion Battery, and Heat Transfer interfaces. A nail is punched into a sandwiched battery consisting of two electrodes and a separator. As soon as the nail connects both ... Per saperne di più
Through-silicon vias (TSVs) allow chips or wafers to be connected vertically, making TSV a crucial technology for 2.5D and 3D packaging. The basic structure of a TSV consists of a deep hole penetrating a silicon substrate, a filling metal (usually copper) in the deep hole, and an ... Per saperne di più
