... Abstract This research investigated the time-dependent stress relaxation and creep performance of McKibben-type artificial soft fabric muscles (ASFMs). The ASFMs are constructed of High Performance Fibers (HPF) encompassing an oversized, pleated, nonstructural fluid bladder. These ASFMs have...

... Abstract Research on the macroscopic phenomenological constitutive model of Haynes 230, which is frequently used as an aero engine combustor liner material, still has important engineering significance. Based on a proposed model for isothermal fatigue and fatigue-creep, a constitutive model...

... decreases with increasing plastic strain, it is important to study creep occurrence, especially during thermal cycles. In this work, a dynamic mechanical analyser (DMA) was used to study the influence of different applied load and temperature on the creep behaviour of the solder during a sequence of cycles...

... of thermal expansion compared with conventional steels is a concern. In addition, Ni-based superalloys have to suffer creep-fatigue random loading because thermal power plants have to compensate the random output of various renewable energies. It was found that the lifetime of Ni-based superalloys under...

... due to creep which causes socket failure due to fatigue and creep interaction. The socket failure at room temperature is determined by fatigue test to obtain S-N curve. Also, stress distribution on the socket is studied at 50 C°. amputee fatigue creep below knee piezoelectric sensor 1...

... 02 08 2012 Highly efficient and compact primary surface recuperators are widely used in the microturbine system. However, creep deformation may occur in the passages of the primary surface sheet due to its thin thickness and long operating time. In this paper, the stress and creep...

... temperatures. In addition, the effects of prior strain rate on relaxation response and on creep behavior following strain controlled loading were examined at temperatures in the range of interest. Positive, nonlinear strain rate sensitivity is observed in monotonic loading at all temperatures investigated...

... Creep damage viscoelasticity-viscoplasticity Electronic Speckle Pattern Interferometry The analysis of the long-term behaviour of polymer matrix composites has to be performed for their stiffness evolution and for their strength changes. Long fiber reinforced polymer matrix composites...

... deformations of the solder alloy. The investigation reveals that the material constants used in the model can be adequately determined from the results of standard creep tests. The constitutive model is validated by comparing the predicted and measured ratchetting results of the solder alloy under different...

... 31 03 2008 The strong interest in ceramic matrix composite for high temperature application arises primarily from their ability to retain good creep behavior. The objective of this work is to investigate the creep behavior of quasi-isotropic woven silicon carbide fabric reinforced...

... presented in detail for the solution of these design problems by a large number of authors in the sixties and seventies. However, it is observed that there is a paucity of reported research investigations on the creep behavior of equipment containing periodic holes such as boiler headers, heat exchangers...

...; oscillatory shear flow, steady shear, and creep. We found that PTAA based ER fluid exhibited viscoelastic behavior and showed the excellent responses under an applied electric field. Moreover, the ER response of this PTAA fluid was amplified with increases in electric field strength, particle concentration...
