Some effects of thermal-cycle-induced deformation in rocket thrust chambers [PDF]

The deformation process observed in the hot gas side wall of rocket combustion chambers was investigaged for three different liner materials. Five thrust chambers were cycled to failure by using hydrogen and oxygen as propellants at a chamber pressure of

Evaluation of the ratcheting behavior of Cr-Mo steel used in CNG tank

Results in Engineering
Compressed natural gas (CNG) tanks, due to the frequent filling and emptying during their service life, are constantly subjected to fatigue loading on the tank's wall, which causes premature failure.

Behavior of confined granular beds under cyclic thermal loading

, 2019
We investigate the mechanical behavior of a confined granular packing of irregular polyhedral particles under repeated heating and cooling cycles by means of numerical simulations with the Non-Smooth Contact Dynamics method.

Assessment methods for Bree-type ratcheting without the necessity of linearization of stresses and strains

International Journal of Pressure Vessels and Piping, 2007
Pressurized component design codes based on design-by-analysis require the evaluation of thermal ratcheting produced by the combination of primary and cyclic secondary stresses. In the current codes for nuclear power components provide domain categorization type evaluation methods of progressive strain, using Miller's or Bree's diagram.

Stochastic Ratcheting on a Funneled Energy Landscape is Necessary for Highly Efficient Contractility of Actomyosin Force Dipoles

, 2017
Current understanding of how contractility emerges in disordered actomyosin networks of non-muscle cells is still largely based on the intuition derived from earlier works on muscle contractility.

Ratcheting Response of Heat-Treated Notched 1045 Steel Samples Undergoing Asymmetric Uniaxial Loading Cycles

Applied Mechanics
The present study evaluates the ratcheting response of notched cylindrical samples made of 1045 steel alloy subjected to asymmetric loading cycles using the kinematic hardening framework, coupled with Neuber’s rule.

Treatment of multiaxial creep-fatigue by strainrange partitioning [PDF]

Strainrange partitioning is a recently developed method for treating creep-fatigue interaction at elevated temperature. Most of the work to date has been on uniaxially loaded specimens, where as practical applications often involve load multiaxiality. It

A comparison of two frameworks for kinematic hardening in hyperelasto-plasticity [PDF]

, 2017
In this work we compare two frameworks for thermodynamically consistent hyperelasto-plasticity with kinematic hardening. The first was formulated by Dettmer and Reese (2004), inspired by Lion (2000), and has been used to model sheet metal forming.
