A study of compression loading of composite laminates

Creator:: Berbinau, Pierre J.
Abstract:: The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

Investigation into the role of strength and toughness in composite materials with an angled incident crack

Creator:: Grimm, Brian A.
Abstract:: Understanding the mechanical behavior of composite materials requires extensive knowledge of fracture behavior as a crack approaches an interface between the bulk material and the reinforcement structure. Overall material toughness can be greatly influenced by the propensity of an impinging crack to propagate directly through the substrate or deflect along...

An experimental approach to analyze large notched composite panels loaded in out-of-plane shear

Creator:: Froemming, Tyler M.
Abstract:: Identifying material characteristics of composites is important in designing any structural system. The aerospace industry relies on these material properties not only to design a functional aircraft, but also a safe and reliable one. Since carbon fiber composites are relatively new materials, little is known about its characteristics under certain...

Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

Creator:: Sutton, Matthew T.
Abstract:: Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

Failure analysis of pre-notched composite laminated plates under four-point bending conditions

Creator:: Arias Gonzales, Sergio
Abstract:: Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...

A force plate for measuring contact forces during dependent transfers onboard aircraft

Creator:: Schafer, Christopher A.
Abstract:: The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

A nonlocal damage theory for laminated plate with application to aircraft damage tolerance

Creator:: Nahan, Matthew F.
Abstract:: Design of commercial aircraft structure, composed of composite material, requires the prediction of failure loads given large scale damage. In particular, a fuselage of graphite/epoxy lamination was analyzed for damage tolerance given a standard large crack that severed both skin and internal structure. Upon loading, a zone of damage is...
