Web15 apr. 2024 · The material point method (MPM) is increasingly being used in multimaterial contact problems. Despite MPM’s advantages for such problems, some aspects of current contact methods are prone to instabilities. The main causes of instabilities are errors in the methods used to calculate normal vector and material separation. WebContact angle hysteresis by tilting method. Tilting method is the second optical method. The droplet is placed on the substrate to be measured and the tilting of the sample is started. The advancing and receding angles are measured at the point at which the droplet starts to move on the substrate. At the same point, the roll-off angle can be ...
