A Large-Strain Poroviscoelastic Model of Brain Tissue

This example demonstrates how to set up a fully coupled poroviscoelastic model of biological tissues. The model is benchmarked by simulating a cyclic uniaxial tension–compression test on human brain tissue.

Indentation of a Cylindrical Battery Cell

Indentation tests are commonly used to evaluate the safety of battery cells by assessing the risk of internal short circuits under external mechanical loads.

This example demonstrates how to set up such a test, in which an indenter is pressed onto a battery cell, causing significant deformation of its components. The analysis is performed using an explicit dynamics approach that accounts for plasticity and contact mechanics.

Phone Drop Test

Drop tests are used to evaluate how consumer products respond to impacts and high accelerations. In this example, the Solid Mechanics, Explicit Dynamics interface is used to numerically simulate a drop test of a mobile phone, highlighting the permanent deformation of the aluminum case and the damage sustained by the glass screen.

Needle Penetration

Modeling the penetration of a needle into soft materials, such as gelatin, involves several complex mechanical challenges, including large deformations, high friction, contact forces, and material failure. This example simulates the needle insertion process into tissue-like materials, using a cohesive zone model to capture the fracture behavior.

Crimping of a Cable Terminal

Crimping is the plastic deformation process used to form an electrical joint between a stranded conductor and a terminal. The process involves complex multisurface contact, including self-contact, as the terminal sleeve is plastically deformed around the wire strands. This example analyzes the crimping of an aviation wire terminal using an explicit dynamics simulation.
