Aeroelastic and Trim Analysis
Patran and MSC Nastran application for aeroelastic analysis and tailoring - Sapienza University of Rome
Subsonic and Supersonic Fixed Wing Projects - Virginia Tech and NASA
The framework supports multiple load-cases analysis as well as different thicknesses for pockets of plate formed by intersection of the stiffeners or uniform panel thickness. The mass of the panel is minimized subjected to constraints on buckling, von Mises stress, and crippling or local failure of the stiffener using global optimization techniques like Particle Swarm Optimization (PSO) or gradient based optimization techniques.Virginia Tech and NASA Subsonic & Supersonic Fixed Wing Projects
Using a common Test and Simulation environment to optimize the Durability Process
Manufacturers are under continuous and increasing pressure to reduce the “Time to Market” of new products while assuring a high reliability level of these products. Durability design and analysis is an essential element in achieving these objectives and involves a multi-disciplinary approach. In order to obtain rapid and realistic life predictions, Simulation and Testing should be used in synergy, each field bringing to the other the necessary information, making the durability process an integrated one.
General Principles of Fatigue Theory
Purely static loading is rarely observed in modern engineering components or structures. By far, the majority of structures involve parts subjected to fluctuating or cyclic loads. For this reason, design analysts must address themselves to the implications of repeated loads, fluctuating loads, and rapidly applied loads. Such loading induces fluctuating or cyclic stresses that often result in failure of the structure by fatigue. Indeed, it is often said that from 80% to 95% of all structural failures occur through a fatigue mechanism.
