An Instability Leading to Failure of Polyethylene in Uniaxial Creep
"... Based on a continuum model, a point of instability is predicted for the uniaxial creep of high density polyethylene. From dead load experiments it has been found that the instability occurs for linear-polyethylene at around 10-12 percent strain, depending upon molecular weight and molecular weight d ..."

A SURVEY OF THE MECHANICS OF UNIAXIAL CREEP DEFORMATION OF METALS.
, 1966
"... summary The time hardening, life fraction and strain hardening hypotheses variously proposed to describe tiniaxisl creep deformation are considered and compared with experimental evidence. It is concluded that the strain hardening hypothesis is the most nearly correct, the experimental strains usual ..."

UNIAXIAL CREEP BEHAVIOR OF V-4Cr-4Ti ALLOY* UNIAXIAL CREEP BEHAVIOR OF V-4Cr-4Ti ALLOY UNIAXIAL CREEP BEHAVIOR OF V-4Cr-4Ti ALLOY
"... Abstract We are undertaking a systematic study at Argonne National Laboratory to evaluate the uniaxial creep behavior of V-Cr-Ti alloys in a vacuum environment as a function of temperature in the range of 650-800°C and at applied stress levels of 75-380 MPa. Creep strain in the specimens is measure ..."

COMPARABILITY OF RESULTS VIA THE MINIATURISED SMALL PUNCH CREEP TEST METHOD AND TRADITIONAL UNIAXIAL CREEP TESTING
"... The Small Punch (SP) test technique is capable of generating tensile, toughness and creep strength data from very small specimens. The ability to sample test material from large components almost non-destructively is accelerating the interest in SP by industry utilising such plant, in particular in ..."

temperatures and at one load level (i.e. almost equivalent to the so called “iso-stress ” method for the corresponding uniaxial tests) are analised in order to check the comparability to uniaxial creep test results. A value of the activation energy QSP = 316 KJ/mol was obtained from the SP tests, quite similar
Prediction of the Constitutive Equation for Uniaxial Creep of a Power-Law Material through Instrumented Microindentation Testing and Modeling+1
, 2013
"... Indentation creep tests and finite element simulations were performed on a model material to show that the constitutive equation for conventional uniaxial creep can be derived using the instrumented indentation testing technique. When the indentation pressure and the indentation creep rate are maint ..."

A STUDY ON ESTIMATION OF INTERNAL PRESSURE CREEP LIFE USING SMALL PUNCH CREEP (SPC) TESTS FOR BOILER PIPES
"... ABSTRACT The small punch creep (SPC) test is possible to predict residual creep life at a high accuracy. But, the results of SPC tests cannot be compared with uniaxial creep or internal pressure creep results directly. In this report, the relationship between SPC test results and uniaxial creep tes ..."

Modelling of rock salt creep
, 2009
"... iii Rock salt deformation behaviour are often said to correspond to that of a very viscosity fluid, hence a rheologic material model could be a good tool for de-scribing the stress-strain relations. This thesis treats the application of a rheo-logic model introduced by Cristescu [1993] as the tool f ..."

work, an internal state variable serving as a work-hardening parameter, failed due to inadequate knowledge of the the total stress-strain relation. Uniaxial creep tests have been performed on rock salt from the Tostrup 5 well and steady-state creep behaviour were observed after approximately 20 days
