Within the Ansys software environment, the distinction between interacting surfaces is crucial for accurate simulation. One surface is designated as the “contact” surface, while the other is termed the “target.” This differentiation allows the software to apply appropriate algorithms for calculating forces, stresses, and deformations at the interface. For instance, in a simulation of a bolted connection, the bolt head might be defined as the contact surface, while the plate it presses against would be the target. This pairing enables the software to model how the bolt load distributes across the plate.
Accurately defining these surfaces is fundamental for predicting real-world behavior in various engineering disciplines, from structural analysis to thermal management. Proper setup ensures realistic simulations of interactions like friction, impact, and pressure distribution, leading to more robust and reliable designs. The evolution of contact mechanics algorithms within Ansys has progressively enabled more complex and accurate simulations, facilitating advancements in fields such as automotive crashworthiness and consumer electronics design.
