 Compression of an Elastoplastic PipeIn offshore applications, it is sometimes necessary to quickly seal a pipe as part of the prevention of a blowout. This example shows a simulation, in which a circular pipe is squeezed between two flat stiff indenters. The model serves as... 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... Combining Elastoplastic and Creep Material ModelsThis 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... Polynomial Hyperelastic ModelThis model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney-Rivlin hyperelastic material model defined by a polynomial. In this example, you... Pressurized Orthotropic ContainerA thin-walled container made out of rolled steel is subjected to inner overpressure. The material is represented with an elastic isotropic model together with Hill orthotropic plasticity. The principal directions of the material follow... Thermally Induced CreepCreep 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... Primary Creep Under Nonconstant LoadIn 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... Arterial Wall MechanicsThis model shows how to implement an anisotropic hyperelastic material for modeling collagenous soft tissue in arterial walls. The hyperelastic material model, called Holzapfel-Gasser-Ogden material, is based on the... Combining Creep Material ModelsThis 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...
