摘要： An aspect of the present disclosure is to precisely define a constant value used in the Monkman-Grant analysis, when estimating remaining life of a high-chromium steel pipe through which high-temperature and high-pressure fluid is allowed to flow. A remaining life estimation method according to the present disclosure is particularly characterized in that a step of obtaining a constant on an accelerated creep test is performed in which a constant indicative of the product of a strain rate and a rupture time in the Monkman-Grant analysis is obtained by multiplying a first coefficient to transform uniaxial rupture ductility into multiaxial rupture ductility, the uniaxial rupture ductility being obtained from a specimen of the high-chromium steel pipe, a second coefficient to amend consumed life of the specimen, and a third coefficient to amend a measured pressure into an assessment pressure.

摘要： A test facility includes a heat source to thermally load a test object being mechanically loaded by rotation imposed by a spin test rig. The heat source can be a quartz lamp controlled to provide a thermal load with a differing phase than the mechanical load. Testing cycles can be run for the test object, with impingement cooling permitting the removal of the thermal load between cycles. The test facility emulates operating conditions in a gas turbine engine to impose realistic thermal and mechanical fatigue stress on the test component.

摘要： Methods for assessing viscoelastic properties of soft tissues are based on detecting an inflection point on a pressure-time plot when air is aspirated from a cavity placed over the tissue sample. A small diameter tube through which air aspiration is conducted is ultimately closed off by tissue being drawn into the cavity causing an abrupt change in pressure slope. First or second derivatives of the pressure-time plot can be used to detect the inflection point. Repeating the test with a different aspiration rates or after a predetermined relaxation time allows determining tissue viscosity and tissue creep in addition to tissue elasticity expressed as Young's modulus.

摘要： A method is disclosed of using external polymeric analytical techniques to predict in-vivo polymeric performance, more particularly, viscoelastic property characterization for performance modeling of biomedical devices that incorporate a polymeric component and are load-bearing during service. Time-Temperature Superposition can be used to accelerate external testing of pertinent properties. Boltzmann's superposition provides a mathematical methodology for determining the time-dependent strain that develops in response to an imposed stress history. The modeling of the present invention provides an opportunity to describe and predict behavior of the device during in-vivo service, as well as it providing a basis for evaluating alternate “candidate” polymers for use in the construction of the device.
