Force Sensing Resistors (FSRs) are manufactured by sandwiching a Conductive Polymer Composite (CPC) between metal electrodes. The piezoresistive property of FSRs has been exploited to perform stress and strain measurements, but the rheological property of polymers has undermined the repeatability of measurements causing creep in the electrical resistance of FSRs. With the aim of understanding t...

mechanism and factors influencing on creep behavior of clay soil have not been understood yet due to its complex structure. in this paper, to investigate the affecting parameters on the creep behavior of the clay soils such as stress level, over consolidated pressure and water pressure, odeometr test are performed in states of single stage, stepwise and overloaded-unloaded and the creep mechani...

materials exhibit significant creep behavior at temperatures above 40% of their absolute melt temperature. lead, tin and their alloys are such materials which experience significant creep behavior in room temperature. one of the most important applications of the tin-lead alloys is soldering electronic circuits in electronic industry, and for lead are isolation walls and wet batteries. room tem...

T o scientists, creep refers to the very slow motion of a solid, or that of an extremely high viscous fluid, in response to an external stimulus. For creep to occur, atoms must move in a concerted or collective way. Creep motion matters in a variety of fields: In materials science, creep of grain boundaries makes it challenging to predict the longevity of material properties with potential impl...

In the current industry, steel–concrete composite beams are used in large-span bridges and super-high-rise building structures due to their excellent overall performance. Concrete’s creep slip effects combined structure can adversely affect structure, thus affecting safe use of buildings. It is necessary study mechanical properties considering slip. order further under creep–sliding coupling, t...

The contraction dynamics of end and center regions of single fibers have been measured during fixed-end tetani. Experimental control and data acquisition are provided by a digital system that can acquire diffraction data as fast as every 260 microseconds for 300-700 ms. Tension records are simultaneously displayed on a storage oscilloscope. Resting sarcomere length variation between the end and...

Time-dependent creep stress redistribution analysis of thick-walled FGM spheres subjected to an internal pressure and a uniform temperature field is investigated. The material creep and mechanical properties through the radial graded direction are assumed to obey the simple power-law variation throughout the thickness. Total strains are assumed to be the sum of elastic, thermal and creep strain...

Enzymatic treatments were applied to rat motion segments to establish structure-function relationships and determine mechanical parameters most sensitive to simulated remodeling and degeneration. Rat caudal and lumbar disc biomechanical behaviors were evaluated to improve knowledge of their similarities and differences due to their frequent use during in vivo models. Caudal motion segments were...

OBJECTIVE To determine the effect of creep developed in the anterior cruciate ligament and other viscoelastic knee structures on the function of the flexor and extensor muscles of males and females. DESIGN Static load applied to the proximal tibia of young healthy male and female subjects in a laboratory setting with maximal voluntary knee flexion and extension performed before and after the ...
