The effect of prestress force value on the dynamic characteristic members characteristics been excessively argued among researchers till now. This study aims to perform a statistical method based meta-analysis investigating influence prestressing first mode shape natural frequency prestressed reinforced concrete member and related loss. prior trials extracted from ScienceDirect, Scopus, Clariva...

In this paper, the fuel pump impeller was selected as a typical airborne equipment for investigation of random vibration fatigue. First, based on platform ANSYS WORKBENCH, reasonable calculation FSI carried out. Then, stress transferred to modal analysis, and prestress-structure extracted. Through response obtained. The Palmgren Miner rule Dirlik fatigue method used calculate life, result consi...

Understanding sub-Rayleigh-to-intersonic transition of mode II cracks is a fundamental problem in fracture mechanics with important practical implications for earthquake dynamics and seismic radiation. In the Burridge–Andrews mechanism, an intersonic daughter crack nucleates, for sufficiently high prestress, at the shear stress peak traveling with the shear wave speed in front of the main crack...

: The periosteum, a composite cellular connective tissue, bounds all nonarticular bone surfaces. Like Velcro, collagenous Sharpey's fibers anchor the periosteum in a prestressed state to the underlying bone. The periosteum provides a niche for mesenchymal stem cells. Periosteal lifting, as well as injury, causes cells residing in the periosteum (PDCs) to change from an immobile, quiescent state...

For a flexible tension structure, the first thing to do is perform form-finding analysis obtain reasonable initial state of structure. The includes structure's own weight and cable force distribution under additional dead load corresponding geometric configuration. configuration expectations must be ensured consistent with geometry building. This paper used MIDAS software establish zero-state m...

The tensegrity model hypothesizes that cytoskeleton-based microtubules (MTs) carry compression as they balance a portion of cell contractile stress. To test this hypothesis, we used traction force microscopy to measure traction at the interface of adhering human airway smooth muscle cells and a flexible polyacrylamide gel substrate. The prediction is that if MTs balance a portion of contractile...

As typical anchorage-dependent cells myocytes must balance contractility against adequate adhesion. Skeletal myotubes grown as isolated strips from myoblasts on micropatterned glass exhibited spontaneous peeling after one end of the myotube was mechanically detached. Such results indicate the development of a prestress in the cells. To assess this prestress and study the dynamic adhesion streng...

Carbon-fiber reinforced plastic (CFRP) is ideal for bridge reinforcement due to its high strength, light weight, and corrosion resistance. Studies on the friction loss of CFRP tendons in a bending state form an important part advancing application materials external prestressing strengthening technology. To understand magnitude variation interfacial prestressed under conditions, 12 single-bendi...
