(Texas A&M University. Libraries, 1983)A new approach to the characterization of pavement mixtures' toughness based on the J integral concept was developed. The fracture mechanics approach was used to compare fatigue and fracture characteristics of new plasticized ...
-
(Texas A&M University, 2006-08-16)Hot-mix asphalt concrete (HMAC) mixture fatigue characterization constitutes a fundamental component of HMAC pavement structural design and analysis to ensure adequate field fatigue performance. HMAC is a heterogeneous ...

Determination of the mode I delamination fracture toughness of multidirectional composite laminates (Texas A&M University. Libraries, 1988)The objective of this study is to develop and verify a theoretically-based method for characterizing mode I delamination fracture of composite laminates. Attention focuses on the special problems associated with delamination ...
-
(Texas A&M University. Libraries, 1978)Theoretical and experimental investigations of stress and displacement distributions in cracked solids are described. The effect of damaged material in the small highly stressed zone around a crack tip on maximum shear ...
-
(Texas A&M University. Libraries, 1988)It has been proved by many researchers that existing fatigue failure criteria based on constant amplitude loading tests underpredict the fatigue life of asphalt concrete pavements. Unrealistic loading conditions in laboratory ...
-
(Texas A&M University. Libraries, 1986)In most materials, macrocrack extension is accompanied by inelastic phenomena (such as microcracking or plastic deformation) throughout a region surrounding the crack tip. Immediately ahead of the crack tip, strain ...
-
(Texas A&M University. Libraries, 1980)Over the past few decades the aircraft industry has devoted considerable effort incorporating fracture control procedures in the design of their structures. One of the problems confronting aircraft designers is the modeling ...
-
(2020-07-09)Shape memory alloys (SMAs) are capable of recovering large deformations through martensitic phase transformation, a reversible transformation between austenite and martensite, driven by stress and/or temperature variations. ...
-
(Texas A&M University. Libraries, 1992)A work potential based analysis was used to model damage related material nonlinearities in graphite-epoxy laminates. Two work potentials were incorporated. One potential was related to sub-ply damage, such as shear banding ...
-
(Texas A&M University. Libraries, 1985)The influence of material anisotropy (transverse isotropy) on half-plane surface tilt and displacement fields induced by a near-surface crack under uniform pressure or shear is investigated by solving a series of boundary ...
-
(Texas A&M University. Libraries, 1993)A laminated composite pressure vessel subjected to a concentrated laser ablation process has been investigated. The primary goal of this research was to investigate the role of delamination in the failure process. A layered ...
-
(2011-08-08)Polymer coated sheet metal components find diverse applications in many industries. The manufacturing of the components generally involves forming of sheet metal into the desired shape and coating of the formed part with ...
-
(Texas A&M University. Libraries, 1990)The large scatter in cleavage fracture toughness values of steels in the ductile to brittle transition region has made characterization and design difficult. Current weakest link statistical models predict that cleavage ...
-
(Texas A&M University. Libraries, 1987)Experimental methods for determining the existence of a work potential, useful in characterizing material response even in the presence of significant damage, are developed and described. The underlying fracture theory and ...
-
(Texas A&M University. Libraries, 1986)Concepts of elastic fracture mechanics are applied to an airfield pavement material. The material used to conduct the experimental work is a portland cement stabilized fine grained soil. Two primary areas of interest and ...
