Phase i of the proposed research would: 1. extend the bounding solutions for strain ranges, maximum stresses and accumulated strains due to inelastic cyclic loads to include structural discontinuities 2. determine the most effective methods for developing user oriented special computer programs for… More

There are numerous commercial applications which demand highly flexible, ductile materials which still possess adequate strength and creep resistance. we suggest that this combination of properties may be achieved by embedding short, storng fibers into a highly flexible matrix material.by altering… More

Stresses due to pressure and repeated thermal cycling cause progressive material damage during the operation of lwr components and piping systems. the present pro posed research would improve the accuracy of existing s- n fatigue evaluation methods by combining them with the advanced technology of… More

While corrosion fatigue limits the useful life of a large number of mechanical components, there currently are no quantified methods of evaluating this failure mode when making design and manufacturing decisions. such methods would allow the designer to evaluate alternate geometric features… More

DESCRIPTION (provided by applicant): Human powered vehicles provide fundamental and often the sole means of transportation for millions of people throughout the world. For people with particular types of disabilities, such vehicles provide a means to a le ss encumbered lifestyle. A primary… More
