The composite pressure vessels are used in varieties of applications such as automobile, aeronautics and chemical engineering. Besides these, they have become very popular in oil and gas transport industries. These pressure vessels are experience very high internal pressures during their operation. The present paper demonstrates a study on cylindrical section of carbon fiber reinforced polymer ...

The first publication of the work [1] did not present one of the authors' names. Kunalan Ganthel has now been added to the author list. In addition, Habib Sherkat has been added to the Acknowledgements, with thanks for providing help with the use of hyperelastic module of Abaqus Software. Prospects of implant with locking plate in fixation of subtrochanteric fracture: experimental demonstration...

The elastic as well as time-dependent mechanical response of the vocal fold cover (epithelium and superficial layer of the lamina propria) under tension is one key variable in regulating the fundamental frequency. This study examines the hyperelastic and time-dependent tensile deformation behavior of a group of human vocal fold cover specimens (six male and five female). The primary goal is to ...

A. Samani, I. Sack, D. Plewes University of Toronto, Sunnybrook and Women's College Health Sciences Centre, Toronto, Ontario, Canada Synopsis To increase the displacement SNR in breast MR elastography, tissues are compressed significantly. As a result, breast tissues undergo large deformations. This leads to significant geometric and material nonlinearities. In this study, methods for treating ...

Large proximal and smaller distal coronary arteries respond differently to pharmacologic agents, but the role of autoregulation is not known. We examined this role in dogs by cannulating the main left coronary artery and a distal left anterior descending artery branch. With coronary flow held constant, the distal coronary artery pressure and the gradient from proximal to distal artery were prop...

Biomechanical model of soft tissue derived from experimental measurements is critical for developing a reality-based model for minimally invasive surgical training and simulation. In our research, we focus on developing a biomechanical model of the liver under large tissue deformation. This paper presents the experimental apparatus, experimental data, and methods to model the experimental data ...

The reliability of computational models of physical processes has received much attention and involves issues such as the validity of the mathematical models being used, the error in any data that the models need, and the accuracy of the numerical schemes being used. These issues are considered in the context of elastic, viscoelastic and hyperelastic deformation, when finite element approximati...

Elastic compression is recommended in prophylaxis and the treatment of venous disorder of the human leg. However, the mechanisms of compression are not completely understood and the response of internal tissues to the external pressure is partially unknown. To address this later issue, a 3D FE model of a human leg is developed. The geometry is derived from 3D CT scans. The FE model is made up o...

We begin by allowing a gas to occupy a well insulated vessel, where the pressure (Pinitial) is a bit higher than atmospheric pressure (Vinitial and Tinitial are known). The vessel is then opened and closed rapidly, allowing the gas to escape at an intermediate pressure equal to atmospheric pressure (Pinter). The speed with which this is done is crucial, because if there is appreciable heat loss...
