Effect of Hybrid Fibers on Flexural and Tensile Properties of Ultrahigh Performance Fiber-Reinforced Cementitious Composites: Experiments and Calculation
Publisher: ASCE
Abstract: This paper addresses effects of hybrid fibers on the flexural and tensile properties of ultrahigh performance fiber-reinforced cementitious composites (UHPFRCC). The workability, compressive strength, flexural strength, ...
Relations of Radial Vibration of the Arterial Wall to Pulsatile Parameters in Blood Flow for Extraction of Arterial Indices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Given the wide utility of radial vibration of the arterial wall for clinical values, this paper presents a theoretical study on the relations of radial vibration of the arterial wall to pulsatile parameters in blood flow. ...
Radial and Axial Displacement of the Initially-Tensioned Orthotropic Arterial Wall Under the Influence of Harmonics and Wave Reflection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines radial and axial displacement of the arterial wall under the influence of harmonics and wave reflection for the role of axial wall displacement in pulsatile wave propagation. The arterial wall is modeled ...

A Vibrating-String Model for Closed-Loop Wave Transmission and Reflection Between the Aorta and Periphery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A tube-load model is used to reconstruct aortic pressure waveform from peripheral pressure waveform. Yet, the reconstructed aortic pressure waveform is greatly affected by load impedance used. In this work, a vibrating-string ...
Is It Feasible to Reconstruct Aortic Pressure Waveform Based on a One-Dimensional Uniform Model of the Arterial Tree?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on a one-dimensional (1D) uniform model of the arterial tree, various machine-learning techniques have been explored to reconstruct aortic pressure waveform (APW) from peripheral pressure waveform (PPW). This study ...
I-35W Bridge Collapse
Publisher: American Society of Civil Engineers
Abstract: The I-35W bridge over the Mississippi River in Minneapolis, Minnesota, collapsed suddenly on August 1, 2007. This note briefly summarizes an analysis based on original design drawings, an investigation of material evidence ...
Stability of Simple Beam Subjected to Multiple Seismic Excitations
Publisher: American Society of Civil Engineers
Abstract: This technical note analyzes the stability of a simple beam subjected to spatially varying random seismic excitations. It uses the stochastic average method to calculate the stability boundaries of a beam under various ...
Determinate Design and Analytical Analysis of a Class of Symmetrical Flexure Guiding Mechanisms for Linear Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper designs and analyses a class of single-axis translational flexure guiding mechanisms for linear actuators. The proposed flexure mechanisms have symmetrical configurations to eliminate parasitic motion for better ...
