RISComputer Vision Based, Noncontacting Deformation Measurements in Mechanics: A Generational Transformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The remarkable increases in computational speed and memory size that have occurred over the past three decades have impacted virtually every area of scientific inquiry. With regard to the measurement community, the digital ...
Experimental Measurements Using Digital Image Correlation Methods: Brief Background and Perspective on Future Developments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Digital image correlation (DIC) methods initially were developed in the early 1980s to simplify basic in-plane laboratory experiments, modified in the 1990s to obtain full three-dimensional surface displacements and shape ...
Biomechanics of Porcine Renal Arteries and Role of Axial Stretch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is known that arteries experience significant axial stretches in vivo. Several authors have shown that the axial force needed to maintain an artery at its in vivo axial stretch does not change with transient cyclical ...
SUPG-Based Finite Element Method for Direct Material Property Determination Utilizing Full-Field Deformation Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A direct approach is developed using Streamline Upwind Petrov Galerkin (SUPG) concepts to determine the spatially varying property distribution in a nominally heterogeneous material. The approach is based on successful ...
