Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... 詳細を見る

この2ホットアーム熱アクチュエーターのチュートリアルモデルは, 電流伝導, 発熱を伴う熱伝導, そして熱膨張による構造応力とひずみという3つの異なる物理現象を連成します. このモデルには3つのバージョンがあります. マイクロアクチュエーターのジュール熱(thermal_actuator_jh.mph)：このモデルバージョンでは, 電流と温度のみが計算され, 変形は無視されます. COMSOL Multiphysicsライセンスのみが必要です. 熱アクチュエーター (thermal_actuator_tem.mph) ... 詳細を見る

This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values. 詳細を見る

Many engineering structures consist of thin and slender components, where a full solid model will result in extremely many small elements. For such structures, it is much more efficient to use shell or beam elements. In this tutorial and verification model, it is shown how to connect ... 詳細を見る

Concrete structures almost always contain reinforcements in the shape of steel bars ("rebars"). In COMSOL, rebars can be modeled either individually by adding a Truss interface to the Solid interface used for the concrete or using the Fiber subfeature to model their global effect. In ... 詳細を見る

Global equations are a way of adding an additional equation to a model. A global equation can be used to describe a load, constraint, material property, or anything else in the model that has a uniquely definable solution. In this example, a structural mechanics model of a spring is ... 詳細を見る

In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... 詳細を見る

This is a transient model of an electromagnetic plunger with stopper restricting the linear motion. The model consists of a magnetic core, nonmagnetic guider, multi-turn coil, nonmagnetic stopper/blocker, and magnetic plunger attached to the spring and damper at the base. The ... 詳細を見る

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, ... 詳細を見る

Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... 詳細を見る
