The objective of this project was to evaluate and model the effects of moisture, temperature, and combined hygrothermal aging on the durability of a graphite/epoxy woven composite material system. Imposed environmental ...

<p>In this thesis, we theoretically and experimentally investigate the linear and nonlinear dynamic behavior of a frame structure, which frequently occurs in engineering applications. The structure consists of three ...

<p>A crush test fixture for measuring energy absorption of flat plate specimens from an earlier study was redesigned to eliminate the problem of binding of the load transfer platen with the guide posts. Further modifications ...

<p>Four plates with centrally located circular holes were manufactured using a fiber placement technique. With two plates the fibers were steered around the holes in curvilinear trajectories. With the two other plates the ...

<p>Composite materials are considered here as structural materials of highway bridge superstructures. Bridge deck designs can be done according to <i>AASHTO</i>¹ specification and elastic design concepts. </p><p> ...

In this study, we develop a method of life prediction of buried pipe using the concepts of a characteristic damage state and damage accumulation. A stress analysis corresponding to the different types of load during service ...

One of the key issues concerning the durability of composites is the strength and stiffness degradation during service. Traditionally, these materials have been analyzed by methods which do not take into account variations ...

<p>A second-order system of differential equations containing a multifrequency parametric excitation and weak quadratic and cubic nonlinearities is investigated. The method of multiple scales is used to carry out a general ...
