Integrated neural networks approach in CAD/CAM environment for automated machine tools selection

  This paper proposed a new model for integrating neural networks approach in the task of generating process planning for machining features. The main issue of process planning addressed in this paper is the optimization of machine tools selection for mechanical part containing simple and interacting features. First, this proposed method elaborated a knowledge database from the investigation with expert in...

Geometrically nonlinear transient analysis of functionally graded shell panels using a higher-order finite element formulation

  Nonlinear transient analysis of functionally graded curved panels is carried out employing a higher-order C0 finite element formulation. The element consists of nine degrees-of-freedom per node with higher-order terms in the Taylor’s series expansion which represents the higher-order transverse cross sectional deformation modes. The formulation includes Sanders’ approximation for doubly...
