“…49,50 A336 GR 5 can also be found to be applicable in the same domain. 51 The specimens were all fatigued under stress controlled fully reversed (R ¼ À1) tension compression loading, at 20 Hz in room temperature (21 C). Each type of material was tested under the two-stage block loading sequences of high-low and lowhigh.…”

A nonlinear model is proposed in light of the theory of isodamage curves, to assess the cumulative fatigue damage under multistage loading. The isodamage curves were developed through the theory of the S-N fatigue damage envelope, proposed by Pavlou. The adopted functional form of the fatigue damage is a commonly accepted general form. In the present work, a stress function for the fatigue life exponent is derived with the aid of the S-N curve only. In the proposed nonlinear model, no adjusting parameters are necessary for fatigue damage estimation. The fatigue life prediction of the derived model is compared with experimental results of various alloys and existing models.

“…This may be a complex, time consuming, and expensive task. The experimental procedure used for calibration of strainhardening model was described, for example, in [11]. In this case, complex stress was obtained as a result of simultaneous loading of tubular, thin walled specimens by axial load and torque.…”

A new version of failure criterion for additively manufactured materials, together with simple and accurate calibration procedures, is proposed and experimentally verified in this paper. The proposition is based on void growth-based ductile failure models. The failure criterion for ductile materials proposed by Hancock–Mackenzie was calibrated using simple methods and accessories. The calibration procedure allows the determination of failure strain under pure shear. The method is accurate and simple due to the fact that it prevents strain localization disturbing stress distribution at the failure zone. The original criterion was modified to better suit the deformation behavior of additively manufactured materials. Examples of calibration of the original and modified failure criteria for additively manufactured 316L alloy steel is also given in this paper, along with analyses of the obtained results.

This paper reports results of fatigue testing performed under fully reversible, load controlled uniaxial tension-compression. For this scheme of loading definition of relative damage indicator and cumulative damage indicator parameter was given and changes of such parameters during the life of the material were shown for two grades of steel. Simple damage criterion proposed by Johnson [6] was modified to define damage indicator parameter. Definitions of damage parameters based on proposed damage indicator and damage indicator parameter were also given. Damage curves showing changes of damage parameter as the function of the life fraction were shown to illustrate progress of damage during the life of the material.
