Purpose The purpose of this paper is to accurately obtain the deformation of a hybrid robot and rapidly enable real-time compensation in friction stir welding (FSW). In this paper, a prediction algorithm based on the back-propagation neural network (BPNN) optimized by the adaptive genetic...

This paper describes finite element simulations of a manufacturing process chain consisting of forming, weld preparation by milling, laser welding and stress relief heat treatment of an alloy 718 aero-engine part. The work also includes experimental validation with optical measurements of the...

Most of the existing Structural Health Monitoring (SHM) systems are vulnerable to environmental and operational damages. The majority of these systems cannot detect the size and location of the damage. Guided wave techniques are widely used to detect damage in structures due to its sensitivity...

In this paper, a complete non-linear finite element model that could represent the behaviour of the composite columns tested under axial compression in the laboratory was developed. A numerical analyses study was presented based on experimental results for investigating the effects of...
