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

Effect of Aft Rotor on the Inter-Rotor Flow of an Open Rotor Propulsion System [PDF]
The effects of the aft rotor on the inter-rotor flow field of an open rotor propulsion rig were examined. A Particle Image Velocimetry (PIV) dataset that was acquired phase locked to the front rotor position has been phase averaged based on the relative phase angle between the forward and aft rotors.

Wind turbines should have fault ride through capability, and also it can provide damping for the power grid by improving the control strategy. However, the currently corresponding control strategy is designed independent for the fault voltage through ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Natural Frequency of Rotor with Rotor Core.
A rotor core of induction motors consists of many multilayered steel sheets for core which are fixed to a shaft with a shrinkage fit. A bending vibration of rotors with such a rotor core is investigated experimentally. It is shown that the rotor can be modelized by an opening of the multilayered steel sheets and a equivalent Young's modulus of the ...

Optimization of the Production of Rubber Compounds Using Mathematical Models
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...
