In this example, the brittle fracture of a holed plate with a notch is modeled using a phase-field damage model. The geometry of the plate is set up so that a mixed-mode fracture is induced, with dimensions and material properties taken from experimental data. The example shows how to ... 詳細を見る
In this model you study the force-deflection relation of a car door seal made from a soft rubber material. The model uses a hyperelastic material model together with formulations that can account for the large deformations and contact conditions. 詳細を見る
In this example, the mechanical impact of a golf club hitting a golf ball is studied. The contact between the two parts is modeled using a viscous penalty formulation to stabilize the dynamic event. To properly model the large deformation, the golf ball is defined using a hyperelastic ... 詳細を見る
Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... 詳細を見る
A circular metal bar is subjected to uniaxial tension. As an effect, large plastic strains develop. The material is elastoplastic with nonlinear isotropic hardening. As the elongation is increased, the decrease in radius becomes strongly nonuniform, so called "necking". The development ... 詳細を見る
This model shows how to implement an anisotropic, incompressible, hyperelastic material for modeling soft collagenous tissue in arterial walls. The hyperelastic material model implemented is based on the articles: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000), A new ... 詳細を見る
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 ... 詳細を見る
In this tutorial model, different methods for modeling brittle damage are compared in a simple model of a uniaxially loaded bar. The localization of the deformation during fracture is studied using different discretization orders and regularization methods. 詳細を見る
The standard biventricular cardiac model is used to show how to set up fiber directions in a complex geometry. The fibers are then used to model the large deformation of the myocardium with the Holzapfel-Gasser-Ogden anisotropic material model. The Aliev-Panfilov equations are included ... 詳細を見る
A stent is a wire-mesh tube used to open a coronary artery during angioplasty, a process for the removal or compression of plaque. Their design is of significance for percutaneous transluminal angioplasty with stenting. During this procedure, a stent is deployed into the blood vessel by ... 詳細を見る
