Development and validation of a fatigue reliability method for bridging materials

Creator:: Gallops, Sarah
Abstract:: Toughened ceramics, or bridging ceramics, are being developed in an attempt to widen the application base of traditional ceramics, which are brittle and have low resistance to crack extension. The crack growth resistance of these extrinsically toughened ceramics has been shown to increase with crack length, and unlike traditional ceramics,...

The relationship of processing method to the physicochemical changes which occur in processed soft fruits

Creator:: Gallop, Reginald Ambrose
Abstract:: Large amounts of plant tissue are used in the production of many canned, frozen and dried foods. Some of this material is unsatisfactory in appearance and texture, despite careful processing from high quality raw materials. In the present study, the changes induced in soft fruits by controlled heating and freezing...

Effect of peer group presence on the gross motor performance of young children

Creator:: Bates, Margaret K.
Abstract:: The purpose of this study was to determine if passive peer group presence had a significant effect on the performance of students on the Test of Gross Motor Development (TGMD). Fifty-eight volunteer nonhandicapped children aged five, eight, and ten years were subjects for the study. There were 18 subjects aged...

Development, characterization, and piezoelectric fatigue behavior of lead-free perovskite piezoelectric ceramics

Creator:: Patterson, Eric Andrew
Abstract:: Much recent research has focused on the development lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT). Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titanate (PZT) for actuator devices. First, solid solutions based on Li, Ta,...

An application of item response theory to the test of gross motor development

Creator:: Cole, Emily Lynne
Abstract:: The purposes of this study were to (a) provide insight into the use of item response theory (IRT) with psychomotor skills, (b) assess the psychometric properties of the Test of Gross Motor Development (TGMD) using IRT, and (c) provide a basis for future studies of the TGMD using IRT. The...

Fatigue reliability predictions in silicon nitride ceramics based on fatigue behavior, bridging stresses and fracture data

Creator:: Greene, Rawley Brandon
Abstract:: Because of its attractive material properties like high hardness, high toughness, and excellent high temperature strength, materials like silicon nitride are becoming more common for use in high performance applications. However, there have been limited studies of the fatigue behavior of small cracks in silicon nitride and other materials toughened...

The accuracy of parents' perceptions of their preschool children's gross motor abilities

Creator:: Groner, Michael
Abstract:: The purpose of this research was to determine the extent to which parents and professionals were in agreement prior to and following intervention regarding their Judgement of the gross motor abilities of the parents' preschool children. Each child was tested by a professional on the Ulrich Test of Gross Motor...

Durability Assessment of Wood Composites Using Fracture Mechanics

Creator:: Mirzaei, Babak
Abstract:: The advent of synthetic adhesives has transformed the structural applications of wood. However, a persistent issue in adhesively-bonded wood products has been moisture durability. When designing wood based composites, moisture durability will depend on both the wood phase and the adhesive phase. A key question, therefore, is how does one...

Effect of ambient environment on the fracture and fatigue properties of Zr-based bulk metallic glasses

Creator:: Philo, Sarah L.
Abstract:: The effect of ambient environment on the fatigue behavior of two Zr-Ti-Cu-Ni-Be bulk metallic glasses (BMGs) is examined in the present study. The first metallic glass, Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅, was tested to establish the presence of an environmental effect in the fatigue growth curve measured in ambient air. Fatigue growth curves produced...
