Stents are used in biomedical applications to support the inner wall of veins and arteries. Self-expanding stents made of shape memory alloys work differently from balloon-inflated stents, as these stents are crimped to the artery diameter at low temperature then released while the blood ...

The model includes a compilation of benchmark examples included in the text book: Shape Memory Alloys: Modeling and Engineering Applications. D. Lagoudas Ed. Springer 2008. The model uses the Souza–Auricchio model and shows the thermomechanical properties of a NiTi alloy sample ... Mehr lesen
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model, two aluminum plates are joined by generating friction ... Mehr lesen
This example shows how to compute thermally induced stresses in a turbine stator blade using the Thermal Stress, Solid interface. The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore ... Mehr lesen
This example is inspired by a classic bridge type called a Pratt truss bridge. You can identify a Pratt truss by its diagonal members, which (except for the outermost ones) all slant down in span-wise direction towards the bridge’s center. All the diagonal members are subject to tension ... Mehr lesen
In this example, the structural integrity of a cylinder made by a fiber composite is assessed both at the macroscale and at the microscale level. Along with macroscale analyses, structural composites need microscale stress and failure analyses to identify the critical constituents in ... Mehr lesen
In nature, geckos use dry adhesion forces to climb walls. They have inspired researchers to develop synthetic gecko foot hairs to be used in, for example, robot applications. This model contains the nano/micro hierarchy of a synthetic gecko foot hair, where cantilever beams both in nano ... Mehr lesen
A thin-walled frame with a central cutout is subjected to a random load. Although the stresses are far below the yield level of the material, damage accumulates over the load history. The Rainflow counting algorithm is used to define the load scenario and Palmgren-Miner linear damage ... Mehr lesen
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with ... Mehr lesen
These models illustrate some important topics when modeling buckling imperfection. The Euler 2 Buckling Imperfection model shows a simple case with a cantilever beam buckling under compression. Three different buckling modes are combined as initial imperfections. The other model, ... Mehr lesen
