A Model for Analysis of Time-Varying Mesh Stiffness of Helical Gears with Misalignment Errors

open access: yesTransactions of FAMENA, 2021
A mathematical model is proposed to calculate the time-varying mesh stiffness (TVMS) of helical gears under the condition of gear misalignment by combining the slice method. The proposed method aims to reveal the influences of different misalignment errors (centre distance error, action plane error and off action plane error) on the TVMS of helical ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Comparison of the Time Varying Mesh Stiffness of Gears with Single and Multi-Mode Damage

open access: yesKey Engineering Materials
Gears in service conditions experience inevitable tooth damage. These damages can cause changes in the time-varying mesh stiffness depending on the mode of damage. The time-varying mesh stiffness of gears is an essential input in calculating gear dynamic responses.
