Yield Criterion Accounting for the Influence of the Third Invariant of Stress Tensor Deviator. Part II. Analysis of Convexity Condition of the Yield Surface

Engineering Transactions, 2014
General form of yield condition for isotropic and homogeneous bodies is considered in the paper. In the space of principal stresses, the limit condition is graphically represented by a proper regular surface which is assumed here to be at least of C2 ...

Some Remarks on Burzyński’s Failure Criterion for Anisotropic Materials

Engineering Transactions, 2014
Some misstatements appearing in the final form of the failure criterion formulation, de- rived from Burzyński’s hypothesis of material effort for anisotropic bodies, which haven’t been noticed in the literature as yet, are pointed out and discussed ...

Study on fatigue strength in terms of stresses measured by strain gauges attached with its ends to be at weld toes

Nihon Kikai Gakkai ronbunshu, 2023
To evaluate stresses including stress concentration at weld toes for fatigue evaluation of complex shape welded structures such as railway bogie frames, previous studies proposed the stress assessment procedure through measuring strains of actual ...

Proposal of the prediction method for fatigue strength of corroded rails with pitting corrosion by actual stress and stress gradient

Nihon Kikai Gakkai ronbunshu, 2023
Rail corrosion is one of the causes of rail breaks. The relationship between rail corrosion state and fatigue strength is still unclear. Therefore, to accurately estimate the fatigue strength of corroded rails, the prediction method for fatigue strength ...

Yield Criterion Accounting for the Third Invariant of Stress Tensor Deviator. Part I. Proposition of the Yield Criterion Based on the Concept of Influence Functions

Engineering Transactions, 2014
A proposition of an energy-based hypothesis of material effort for isotropic materials exhibiting strength-differential (SD) effect, pressure-sensitivity and Lode angle dependence is discussed. It is a special case of a general hypothesis proposed by the

Fatigue Strength Characteristics of High-Strength Steel

JSME international journal. Ser. 1, Solid mechanics, strength of materials, 1989
In order to clarify the fatigue strength charactaristics of low alloy steels which were strengthed by tempering at low temperature (150∼200°C) after conventional quenching treatment and/or carburizing in generated gas, rotating bending fatigue tests were conducted in laboratory air and dry air using smoothened specimens with 8 mm diameter.

Higher Hamstrings Strength and Stability Are Related to Lower Kinematics Alteration during Running after Central and Peripheral Fatigue

Sensors, 2022
Fatigue can be classified as peripheral or central depending on the extent of its effects. Muscle strength reduction, associated with the appearance of fatigue during running, produces kinetics and kinematics modifications which could lead to an ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
