Application of variable equivalent amplitude for determination of fatigue life of elements subjected to block loading [PDF]

MATEC Web of Conferences, 2021
This paper contains a proposition of a new method of determining the fatigue life of elements subjected to non-stationary loads. The model was based on the determination of the time-variable equivalent weighted amplitude.

The influence of binarity on dust obscuration events in the planetary nebula M 2-29 and its analogues [PDF]

, 2011
The central star of the planetary nebula (CSPN) M 2-29 shows an extraordinary R Coronae Borealis-like fading event in its optical lightcurve. The only other CSPN to show these events are CPD-568032 (Hen 3-1333) and V651 Mon (NGC 2346).

A comparative study of two nuclear steel grades welded joints [PDF]

Archives of Metallurgy and Materials, 2020
In present work, two nuclear grade steel (P91, P92) are joined using the arc welding process. The welded joints were subjected to the heat treatment in order to restore the mechanical properties and overcome the heterogeneity across the joints.

Remaining creep properties and fracture behaviour of P92 steel welded joint under prior low cycle fatigue loading

Journal of Materials Research and Technology, 2020
The alternation of creep properties is unavoidable in welded structures after suffering from cyclic damage, which may lead to the premature failure of power plant units and hard to predict. This work is devoted to clarify the influence of prior low cycle

Confining potential in momentum space [PDF]

, 1992
A method is presented for the solution in momentum space of the bound state problem with a linear potential in r space. The potential is unbounded at large r leading to a singularity at small q.
