Fatigue Strength Estimation Incorporating Residual Stresses

CIRP Annals, 1983
Attempting, to take into account the residual stresses in an estimation of fatigue strength leads to the problem of the calculation criterion. The state of stresses under load in fatigue may be monoaxial, while residual stresses are always multiaxial. If the designer of a part containing residual stresses wants to evaluate its fatigue strength, he must

Residual Strength Of Aramid Rope

Offshore Technology Conference, 1986
ABSTRACT Tensile fatigue test and residual strength test were carried out systematically on the strength reduction of braid-on-braid small size aramid rope in our laboratory. Researches on the residual strength of synthetic fiber rope after cyclic loading were rare, although researches on relationship between ...

Residual Strength of Metal Structures

1996
Abstract This article discusses the conditions for collapse in center-cracked panels and describes the energy criterion for fracture. Measurement of toughness of any material by means of tensile and crack test is discussed. The procedures to be followed for linear elastic fracture mechanics cases are reviewed, along with elastic-plastic ...

Residual strength of pipelines with dents

Materials Science, 1999
We show the urgency of developing methods for prediction of the ultimate load of ductile fracture for defects of the dent type in pipelines. We propose an idealized model of the limiting plastic state of a pipe with infinite dent along it. We obtain formulas for engineering calculations and analyze them.

Safety Factor and Residual Strength

2003
Figure 1 shows a rectangular plate made of 2024-T3 aluminium alloy containing a lmm central crack. The operational stress is σ=200 MPa at R=0. Determine the resid- ual strength that would allow a residual strength safety factor of 1.5 after 20,000 cycles.

Residual Compressive Strength of Heated Concrete

Architectural Science Review, 1993
Test results of a study designed to analyse the effect of elevated temperatures on the compressive strength of concrete incorporating factors such as water-cement ratio, aggregate-cement ratio, time of exposures are presented. It was shown that water-cement ratio is not a sensitive factor, while the hours of exposure to heat and the concrete mix are.

The Residual Strength of Confined Concrete

Advances in Structural Engineering, 2010
Structural engineers have long recognised the importance of member ductility in the design of reinforced concrete members to overcome uncertainties in the design procedure as well as in absorbing energy due to dynamic loads such as earthquakes, impact and blast loads.

Residual‐strength determination in polymetric materials

Journal of Rheology, 1981
Kinetic theory of crack growth is used to predict the residual strength of polymetric materials acted upon by a previous history. Specifically, the kinetic theory is used to characterize the state of growing damage that occurs under a constant‐stress (load) state.

Residual strength characteristics of Bothkennar clay

Géotechnique, 1992
The Paper describes a series of ring shear experiments which were performed to assist the interpretation of instrumented pile tests carried out at Bothkennar. Data are presented from soil-soil and soil-interface experiments. The interface used was a sand blasted annulus of stainless steel and tests were made at a variety of displacement rates.

Drained Residual Strength of Cohesive Soils

Journal of Geotechnical Engineering, 1994
Results of torsional ring shear tests on cohesive soils reveal that the drained residual strength is related to the type of clay mineral and quantity of clay‐size particles. The liquid limit is used as an indicator of clay mineralogy, and the clay‐size fraction indicates quantity of particles smaller than 0.002 mm.
