Cyclic degradation
WebApr 12, 2024 · The repeated cyclic loading has multiple influences on the degradation of the superconducting tape, unlike simple tension, bending or torsion. Changes in the FUS values among and within the constituent layers of REBCO tape when subjected to tensile, bending and torsional repeated cyclic load are discussed in detailed. WebThe results reveal that the cyclic degradation parameter, t, which measures the rate of cyclic degradation with the number of cycles, increases substantially with f and decreases with σ vc ′. If f is increased 10 times, t may increase by 20–50%. If σ vc ′ is increased from 220 to 680 kPa, the t parameter may decrease by 20–38%.

WebJul 1, 2024 · The cyclic accumulation model extends the viscoplastic Creep-SClay1S model as presented in Sivasithamparam et al., 2015, Gras et al., 2024. This model was chosen as a starting point, because it accounts for fundamental features of natural soft soil behaviour, such as anisotropy, bonding and rate-dependence. WebDec 31, 1995 · Abstract: In this paper, a finite-element model is developed in which the nonlinear soil behavior is represented by a hyperbolic relation for static load condition and modified hyperbolic relation, which includes both degradation and gap for a cyclic load condition. Although batter piles are subjected to lateral load, the soil resistance is also …
WebApr 5, 2024 · This review aims to discuss the synthesis of various polyacetals by CROP and their degradation properties from the perspectives of (1) polymerization of cyclic acetals, dioxepins, and hemiacetal esters, (2) copolymerization of cyclic acetals with heterocyclic or vinyl monomers, and (3) degradation and recycling properties of the related polymers. WebThe tested results compared with three soils were sand, Masado (weathered soil), and clay. Clay was used to contrast characteristics of strength and stiffness of nonplastic soil with those of plastic soil. Through comparing results from cyclic DSST, cyclic strength degradation of non-plastic silt was faster although cyclic strength was smaller.
Numerous cyclic nucleotide phosphodiesterases (PDE) can degrade cGMP by hydrolyzing cGMP into 5'-GMP. PDE 5, -6 and -9 are cGMP-specific while PDE1, -2, -3, -10 and -11 can hydrolyse both cAMP and cGMP. Phosphodiesterase inhibitors prevent the degradation of cGMP, thereby enhancing and/or prolonging its effects. For example, Sildenafil (Viagra) and si… WebOct 1, 2013 · As a result, in most of the cyclic soil models, substantial decrease of shear modulus of soil with the progression of loading cycle was incorporated, addition to the standard non-linear backbone curves [1], [3].
