Shakedown analysis of a composite cylinder with a cross-hole [PDF]

, 2011
In this study, both the lower and upper bound shakedown limits of a closed-end composite cylinder with or without a cross-hole subject to constant internal pressure and a cyclic thermal gradient are calculated by the Linear Matching Method (LMM ...

CRYOGENIC RATCHETING OF PRESTRAINED AUSTENITIC STAINLESS STEEL S30408

Jixie qiangdu, 2020
Taking advantage of the EUM-25 K20 tension-torsion fatigue testing machine by CARE,the cryogenic uniaxial ratcheting tests were carried out for the S30408 specimens with and without weld,and with 0%,8%,and 12% pre-strains at110 K.

Experimental and Numerical Analysis of Ratcheting Behavior of Super Duplex SAF2507 Stainless Steel Under Uniaxial Loading

Applied Sciences
Super duplex SAF2507 stainless steel is widely used in petrochemical piping systems during the transport of substances. The pipelines are subjected to cyclic loads due to road vibration and internal pressure, which causes the ratcheting behavior. In this

Microscopic origin of granular ratcheting

, 2007
Numerical simulations of assemblies of grains under cyclic loading exhibit ``granular ratcheting'': a small net deformation occurs with each cycle, leading to a linear accumulation of deformation with cycle number.

Near-tip strain ratchetting and crack growth at elevated temperature [PDF]

International Journal of Fatigue, 2016
Abstract In this work, we have extended our earlier work on the concept of ratchetting strain as a crack driving force (Tong et al., 2013), to examine the crack growth of a nickel-based superalloy at selected temperatures in vacuum under both fatigue and fatigue-creep loading conditions.
