Measurement and Isolation of Thermal Stress in Silicon-On-Glass MEMS Structures
Sensors, 2018 The mechanical stress in silicon-on-glass MEMS structures and a stress isolation scheme were studied by analysis and experimentation. Double-ended tuning forks (DETFs) were used to measure the stress based on the stress-frequency conversion effect ...

A stress free model for residual stress assessment using thermoelastic stress analysis [PDF]
, 2014 Thermoelastic Stress Analysis (TSA) has been proposed as a method of obtaining residual stresses. The results of a preliminary study demonstrated that when Al-2024 plate containing holes that were plastically deformed by cold expansion process to 2% and ...

Direct measurement of the contact normal stress distribution between two smooth joint surfaces
, 2016 The shear strength of rock joints is highly depended upon the failure mode of joint asperity. At lower normal stress slide-up of one asperity up over another mode, however at high normal stress the joint asperities are sheared off at the base.

Reduced Rib Synchronous Reluctance Motor for Traction Applications
Advances in Electrical and Computer Engineering, 2019 This paper proposes a variable width reduced rib rotor structure for Synchronous Reluctance (SynRel) Motor. In convention supporting iron ribs are introduced in transversally laminated anisotropic (TLA) type rotors of SynRel motor to increase the ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Research Progress on Measurement Methods and Influence Factors of Thin-film Stress
Journal of Aeronautical Materials, 2018 With the size of thin-film electronic devices decreasing, the film stress became an important reason for the failure of thin film devices. Film stress not only affected the membrane structure, but also associated with film optics, electricity, mechanics ...
