1. On efficient and adaptive modelling of friction damping in bladed disks
Sammanfattning : This work focuses on efficient modelling and adaptive control of friction damping in bladed disks. To efficiently simulate the friction contact, a full-3D time-discrete contact model is reformulated and an analytical expression for the Jacobian matrix is derived that reduces the computation time drastically with respect to the classical finite difference method.

2. Wave-actuated Preform Infiltration Routines in MMC Production
Sammanfattning : The implementation of highly magnetostrictive wave-actuator techniques in preform infiltration processes for metal-matrix composite production is described. Metal matrix materials require additional methods to handle the content, shape and position of the ceramic reinforcements, which are not required for metal alloy casting. LÄS MER
3. Modelling and design approaches of magnetostrictive actuators
Sammanfattning : A magnetostrictive material elongates when it is subjected to a magnetic field. This effect can then be used to design powerful actuators. LÄS MER
