In this example, monotonic and cyclic triaxial tests are simulated using the Hardening Soil Small Strain material model. The model captures the effects of small strain stiffness and hysteresis under cyclic loading. The stress-strain relationship matches the hyperbolic curve reported in ... Mehr lesen
Fatigue testing of nonlinear materials with creep mechanism is a time-consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is ... Mehr lesen
In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Mehr lesen
Squeezed-film gas damping is a critical aspect of many MEMS transducers and actuators. In accelerometers, for example, inertia produces a motion that the device detects. A typical structure connects a large proof mass to surrounding structures with elastic beams, which forms a mechanical ... Mehr lesen
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Mehr lesen
This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... Mehr lesen
This is a benchmark model involving stick-slip friction of a ring rolling inside another ring. The displacement of the inner ring is computed and compared to the analytical result. This model also shows how to tackle friction dominated contact problem. Mehr lesen
A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... Mehr lesen
This example reproduces a NAFEMS benchmark in which a plate with an angle crack is subjected to tensile loading. The J-integral is calculated and the stress intensity factors for Mode I and Mode II are compared to the benchmark results for several crack angles. Mehr lesen
This conceptual example shows how to handle a transient contact problem with stick-slip friction transition. A soft hollow pipe subjected to gravity is released at the top of a halfpipe. The pipe motion varies between sliding and rolling, depending on its position in the halfpipe and its ... Mehr lesen
