Initial development of a multiscale progressive damage and failure analysis tool for laminated composite structures is presented. The method models microdamage at the lamina level with the thermodynamically based Schapery Theory. Transverse cracking and ber breakage, considered failure mechanisms in this work, are modeled with failure criteria evaluate at the micro-constituent level using the G...

A novel experimental procedure for the testing of ceramic coatings in quasi-static and dynamic torsion is presented. The tests were performed on a Kolsky bar apparatus modified for torsion loading. High-speed photography was used to take snapshots of the surface of the specimen gage during loading, and digitally correlated to determine the full displacement and strain fields. Microand nanoAl2O3...

Silicon dioxide thin film is a common component in electronic devices and in MEMS, but its mechanical properties have rarely been studied. Techniques have been adapted and developed to conduct tensile tests on 1.0 μm thick silicon dioxide specimens that are 100, 150, and 200 μm wide and either 1 or 2 mm long. One end of the specimen remains fastened to the substrate, and the other is glued to a...

Despite considerable advances in the understanding of thyroid gland biology, correctly diagnosing thyroid nodules and treating high-grade thyroid carcinoma remains challenging. Cancer/testis (CT) antigens have emerged as potential diagnostic tools as well as targets of potential cancer vaccinations. In the present study, a total of 117 patients who underwent surgical therapy for thyroid disease...

The objective of this study was to investigate the possibility of a generic rating curve with a small number of adjustable parameters for the restricted class of bedrock step-pool rivers. The motivation for this study arose from Utah Valley University’s long-term program of groundwater development in the Trans-Mexican Volcanic Belt, which requires hydrographs for bedrock step-pool rivers near r...

Abstract This article describes the mixed-methods approach used by Gender and Adolescence: Global Evidence (GAGE) research programme. It discusses how qualitative quantitative methods can be both in isolation combined to learn about lives of adolescents low- middle-income countries (LMICs), focusing on methodological ethical approaches reach socially marginalised (including with disabilities, n...

INTRODUCTION Although bulk post-yield behavior of bone has been extensively reported in the literature, its underlying mechanism at ultrastructural level is still poorly understood. Lack of such knowledge has significantly hindered our understanding of age-related deterioration in bone quality. To address this issue, a mechanistic understanding of the post-yield behavior of bone becomes necessa...
