Development of a decentralized artificial intelligence system for damage detection in composite laminates for aerospace structures
Kral, Zachary Tyler (Wichita State University, 2013-12)Because of economic impact that results from downtime, aircraft maintenance is an important issue in the aerospace industry. In-service structures will decay over time. Compared to low-cycle loading structures, aerospace ... -
Development of an artificial neural network damage detection module for a structural health monitoring system
Kral, Zachary Tyler (Wichita State University, 2009-05)Aircraft, wind turbines, or space stations are expected to remain in service well beyond their designed performance lifetime. Consequently, maintenance is an important issue for aircraft or aerospace structures. This ... -
The effects of sealants and surface treatments on the faying surface of swept friction stir spot welds
Brown, Jeremy Micah (Wichita State University, 2008-12)The goals of this project were to determine and document the effects of sealants and surface treatments have on the ultimate strength, fatigue life, and corrosion resistance of swept Friction Stir Spot Welded (FSSW) joints. ... -
Models and methods for bird strike load predictions
Nizampatnam, Lakshmi S. (Wichita State University, 2007-12)Typical bird shapes used in numerical bird strike analyses include a number of primitive geometries, such as the right circular cylinder, hemi-spherical cylinder, sphere and ellipsoid. There are also some simplifying ... -
Performance evaluation of discontinuous friction stir welding
Merry, Joshua D. (Wichita State University, 2011-12)Friction stir welding has been shown by previous investigators to have many advantages over traditional metal joining practices. Friction stir lap welds and friction stir spot welds have been shown to be stronger than ... -
Viscoelastic relaxation in bolted thermoplastic composite joints
Schmitt, Ron R. (Wichita State University, 1991-12)Results from a research program to investigate the long term effects of through-the-thickness fastener clamp-up force (preload) relaxation on the strength of mechanically fastened joints for two graphite/thermoplastic composite ...
