Biaxial Behavior

In this work the biaxial behavior of 316 stainless steel is studied under the lens of critical plane approach. A series of ten experiments were developed on dog bone shape hollow cylindrical specimens made of type 316 stainless steel. Five different loading conditions were assessed, with (i) only axial stress, (ii) only hoop stress, (iii) proportional combination of axial and hoop stresses, (iv) non-proportional combination of axial and hoop stresses with square shape and (v) non-proportional combination of axial and hoop stresses with L-shape. The fatigue analysis is performed following four different critical plane theories, namely Wang-Brown, Fatemi-Socie, Liu I and Liu II. The efficiency of all four theories is studied in terms of the accuracy of their life predictions.

Creep Loading

A phenomenological approach, already used for other materials, is applied for the prediction of the behavior of 316 stainless steel under fatigue, creep or combined fatigue-creep loadings. The approach is based on the reduction of either the fatigue limit or the creep strength due to damage accumulation. For multilevel loading, an interaction parameter is introduced to account for the interaction effect between two different loading levels. Some particular aspects concerning the application of the procedure are discussed and the life predictions are compared with those obtained by some other techniques. The essential characteristic of the proposed approach is to provide a reasonably good prediction of life for the material subjected to the prescribed loadings using material constants which are determined through minimal experimental data.

Hoop Stresses

A method is proposed for measurement of the hoop stress in an axisymmetric residual stress field in cylinders in which the axial stress is independent of the axial coordinate. The method involves measuring strains at the outside surface while an axial crack is cut progressively from the outside. Experimental results are presented for two short cylindrical rings cut from a long quenched cylinder. Good general agreement is obtained with X-ray and hole drilling measurements of residual stresses.

Life Predictions

Based on critical plane approach, this article develops a new damage parameter through combing the equivalent strain energy aspect for multiaxial fatigue analysis, which includes no additional fitted parameters and overcomes the deficiency of using only equivalent stress/strain criterion separately under multiaxial loadings. Then, experimental data of GH4169, TC4, Al 7050-T7451 alloys under different loading conditions are applied for model validation and comparison with other four models. Results indicate that the proposed damage parameter yields better multiaxial fatigue life predictions than others.

Critical Plane Approach

In this work, the multiaxial fatigue behaviour of 316 and 304 stainless steel was studied. The study was based on the critical plane approach which is based on observations that cracks tend to nucleate and grow in specific planes. Three different critical plane models were employed to this end, namely Fatemi–Socie (FS), Smith–Watson–Topper (SWT) and the newly proposed Sandip–Kallmeyer–Smith (SKS) model. The study allowed equi-biaxial stress state, mean strain and non–proportional hardening effects to be taken into consideration. Experimental tests including different combinations of tension, torsion and inner pressure were performed and were useful to identify the predominant failure mode for the two materials. The results also showed that the SKS damage parameter returned more conservative results than FS with lower scatter level in both materials, with prediction values between FS and SWT.

Degrees Of Severity

An axisymmetric finite element model is used to evaluate the effect of large initial tube-tubesheet radial clearance and the effect of grooves machined in the tubesheet hole on the distributions and magnitudes of the radial deformation of expanded tube walls, residual contact stress, residual hoop stress, and residual axial stress along the expanded length of the tube and in the transition zone. The results have revealed the presence of residual axial stresses and residual hoop stresses in the inside and outside surfaces of the tubes with various degrees of severity. These tensile residual stresses may cause crack initiation and propagation and may lead stress corrosion cracking in corrosive environments.
