TL;DR: The effect of noise on a PNN based uncertainty quantification algorithm is explored and the convergence of the proposed algorithm for stochastic natural frequency analysis of composite plates is verified and validated with original finite element method (FEM).

TL;DR: In this article, a numerical and experimental investigation on unnotched and open-hole tensile characteristics of fiber-steered variable-axial composite laminates was conducted, where the fiber path was obtained from an optimization framework considering manufacturing characteristics of the Tailored Fiber Placement (TFP) process.

TL;DR: The current work on optimization of the linear buckling behavior of variable-axial (VA) shells shows both the potential of using VA-configurations to exploit their tailoring ability and the capabilities of the current optimization framework to improve and optimize the behavior of VA structures.

TL;DR: In this paper, a methodology to optimize an anisotropic composite structure, comprising in performing cross-section optimization of a topologically optimized structure through an evolutionary optimization using a GA, is presented.

TL;DR: The software GEPARD (Gepard Enabled PARticle Detection) allows for acquiring an optical image, then detects particles and uses this information to steer the spectroscopic measurement, which ultimately results in a multitude of possibilities for efficiently reviewing, correcting, and reporting all obtained results.
