On the applicability of Miner’s rule for multiaxial fatigue life calculations under non-proportional load histories [PDF]

Fracture and Structural Integrity, 2017
Fatigue design routines and computer codes must use some damage accumulation rule to deal with variable amplitude loadings (VAL), usually Palmgren-Miner (or Miner’s) linear rule for lack of a clearly better option.

Axial-torsional fatigue and cyclic deformation of 304L stainless steel at room temperature [PDF]

MATEC Web of Conferences, 2019
This work investigates the axial-torsional fatigue and cyclic deformation behaviour of 304L stainless steel at room temperature. Four fully reversed strain-controlled loading paths (axial, torsional, proportional axial-torsional, and 90º out-of-phase ...

Influence of Material Ductility on Fatigue Life under Multiaxial Proportional and Non-Proportional Normal and Shear Stresses [PDF]

MATEC Web of Conferences, 2019
Current experiences show that a non-proportional loading of ductile materials such as wrought steels, wrought aluminium or magnesium alloys, not welded or welded, causes a significant fatigue life reduction under an out-of-phase shear strain or shear ...

Low cycle fatigue life prediction of 63Sn-37Pb solder under proportional and non-proportional loading

, 2019
Multiaxial fatigue tests were conducted on 63Sn-37Pb solder specimens under proportional and non-proportional axial/torsional loading. The von Mises equivalent stress and strain are found to be fitted by the Ramberg-Osgood relationship.

Fatigue Equivalent Stress State Approach Validation in Non-conservative Criteria: a Comparative Study

Latin American Journal of Solids and Structures
This paper is concerned with the fatigue prediction models for estimating the multiaxial fatigue limit. An equivalent loading approach with zero out-of-phase angles intended for fatigue limit evaluation under multiaxial loading is used.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Fatigue damage model of woven glass-epoxy fabric composite materials

Journal of Materials Research and Technology, 2020
Based on the Stiffness degradation rule of woven glass fiber composite under fatigue loading, a phenomenological fatigue damage model containing two material parameters in which first is directly proportional to the fatigue life and second is inversely ...

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Experiments on Damage and Failure Behavior of Biaxially Loaded Specimens under Non-Proportional Load Paths

Physical Sciences Forum, 2022
This paper discusses new experiments with the X0-specimen taken from steel sheets and numerical simulations to investigate the influence of proportional and non-proportional loading on damage and failure processes in the moderate stress state regime. The
