带接触的动力学常被表述为一个约束优化问题。这种方法允许以集成方式处理非穿透和摩擦约束。随着计算力学领域的发展，我们设计了一种算法，用于在最先进的基于约束的接触求解器的背景下添加粘合剂接触约束的模拟。我们表明，隐式附着力约束可以处理与现有的求解器的微小变化，我们证明了我们的算法在各种各样的对象，包括质量弹簧布，体积有限元模型和刚体。
Dynamics with contact are often formulated as a constrained optimization problem. This approach allows handling in an integrated manner both non-penetration and frictional constraints. Following developments in the computational mechanics field, we have designed an algorithm for adding the simulation of adhesive contact constraints in the context of state-of-the-art constraint-based contact solvers. We show that implicit adhesion constraints can be handled with minor changes to existing solvers, and we demonstrate our algorithm on a diverse range of objects, including mass-spring cloth, volumetric finite-element models, and rigid bodies.
