ON THE ESTIMATION OF VON MISES EQUIVALENT STRESS IN RANDOM VIBRATION ANALYSIS [PDF]
Proceedings of the XI International Conference on Structural Dynamics, 2020 Linear random vibration analysis aims to the probabilistic characterization of response functions; classical procedures are targeted to the time histories of output kinematic variables, such as displacement, velocity and acceleration, and to parameters which are linearly related to them, such as internal forces, deformations, stress components ecc ...

Von Mises stresses on Mushroom-loop archwires for incisor retraction: a numerical study [PDF]
Dental Press Journal of Orthodontics, 2020 ABSTRACT Objective: To perform a numerical simulation using FEM to study the von Mises stresses on Mushroom archwires. Methods: Mushroom archwires made of titanium-molybdenum alloy with 0.017 x 0.025-in cross-section were used in this study. A YS of 1240 MPa and a Young’s modulus of 69 GPa were adopted.
