An outer-rotor permanent magnet (PM) synchronous machine (OR-PMSM) with amorphous stator core (OR-PMSMASC) is proposed in this paper, which exhibits higher efficiency than conventional silicon steel PM machines. On the basis of the electromagnetic characteristics of the amorphous alloy material (AAM), the general design of the proposed machine is studied, including the structure parameters and the...
Low-velocity impact on the free edge of composite stiffener is considered as a critical factor on the loss of compression strength. This paper proposes a phenomenologically-based mechanical finite element model for the Compression-After-Edge-Impact (CAEI) failure prediction of the composite panel stiffened with T-shaped stiffeners, of which the web is subjected to edge impact damage. Based on the...
A phenomenological-based mechanical finite element model is developed for the prediction of ultimate compression loads and failure modes of wing relevant composite panels stiffened with I-shaped stiffeners, of which the edge is subjected to impact loading. The initiation of intralaminar failure including fiber and inter-fiber fracture is evaluated by Puck criteria, and its evolution is assumed to...
