Snap Hook

This model simulates the insertion of a snap hook in its groove. Fasteners like this are common in the automotive industry, for example, in the control panel of a car. In this case it is important to know the force that must be applied in order to place the hook in the slot but also the force needed to remove it. From a numerical point of view, this is a highly nonlinear structural analysis, ...

Pressurized Orthotropic Container

A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, one of the three material principal directions—the out-of- plane direction— has a higher yield stress than the other two. Hill’s orthotropic plasticity is used to model the differences in yield strength. The model also shows how to define and use curvilinear ...

Combining Elastoplastic and Creep Material Models

This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by a fluctuating pressure applied to the internal surface of the cylinder. This load case involves two ...

Thermally Induced Creep

Creep is an inelastic time-dependent deformation which occurs when a material is subjected to stress at sufficiently high temperature, say 40% of the melting point or more. Experimental creep data (using constant stress and temperature) often display three different types of behavior for the creep strain rate as function of time: In the initial primary creep regime the creep strain rate ...

Combining Creep Material Models

This model illustrates how to combine together different Creep material models. Here a Norton-Bailey creep material (primary creep) is combined with a Norton creep material model (secondary creep). This model requires the model thermally induced model and is a modification of the Model Library model Thermally Induced Creep.

Sheet Metal Forming with Orthotropic Plasticity Hill '48

Metal Forming is the metalworking process of reshaping metal parts through mechanical deformation without adding or removing material. This is mainly based on plastic deformation that enables permanent deformation of the bodies. Here, a numerical simulation of the sheet metal forming process was carried out using an orthotropic material law for metal plasticity (Hill '48). Different forming ...

Elastoacoustic Effect in Rail Steel

The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states within structures. This example model studies the elastoacoustic effect in steels typically used in railroad rails. The analysis is based on the Murnaghan ...

Primary Creep Under Nonconstant Load

In this model example, you will study the creep behavior of material under non-constant loading. You will model the primary creep using a Norton-Bailey law and study the difference between the time hardening and the strain hardening methods available in COMSOL Multiphysics. The model is taken from NAFEMS Understanding Non-Linear Finite Analysis Through Illustrative Benchmarks. The load consist ...

Inflation of a Spherical Rubber Balloon - Membrane Version

The purpose of this model is to illustrate how the Membrane interface can be used to model thin hyperelastic structures. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane interface is used instead of the Solid Mechanics interface.
