摘要： The present invention provides a polymer indentation method and tester that includes measuring the time taken by a polymeric material to recover a set portion of an initial deformation and use this duration as a material degradation indicator. The recovery time was found to be more sensitive to cable degradation than the specific compressive stiffness (or indenter modulus) measured during the indentation phase, and this high sensitivity was achieved for both thermally aged and irradiated polymer samples.

摘要： An apparatus for conducting demonstrations of the softness properties of consumer products and other materials, plus a method for conducting such demonstrations, is provided. A sample of paper towels, toilet tissue, or facial tissue, or other consumer products is placed in the apparatus. The apparatus drops an egg or other fragile object onto the sample, or the egg may be dropped from an operator's hand into the apparatus and onto the sample. By displaying the egg or fragile object as it either lands safely on a sample or is destroyed on impact, the operator can visually demonstrate to an average consumer either the softness properties of the sample, or the lack thereof. A method of preparing samples in a consistent manner is also provided to ensure that results are as fair, uniform and repeatable as possible.

摘要： A sensor is described for detecting the force applied to or by soft material, and that is thus able to measure the stiffness of a soft material. The sensor comprises a sensor body into which is supplied a fluid under pressure. At least one sensor members are provided that are arranged to project from the sensor body under the pressure exerted thereon by the fluid. A sensor member displacement detection system is also provided, that is preferably optically based using optical fibres to illuminate the sensor member and that measures the modulation of the light reflected from the sensor member as the member is displaced against the pressure of the fluid to detect and measure the displacement. From the measured displacement an estimate of the force being applied to the sensor member can be obtained. The sensor is of a small size suitable for use during MIS or catheterisation procedures. Preferably the sensor is constructed of non-metallic material such that it is MRI compatible.

摘要： The invention is an indenter tip that is modified to permit both compression testing and tensile testing on samples having dimensions smaller than approximately 1 μm. The modified indenter tip has both a surface that can be used to apply compressive forces, and tines that can be used to engage a free end of a specimen to be tested in tension. The apparatus used to perform the tests includes elements of a scanning electron microscope that permit visualization of the specimen to be tested and the modified indenter tip, so as to permit appropriate alignment and engagement of the same. The apparatus also includes elements of a microindenter that provide mechanical manipulation of the relative position and orientation of the modified indenter tip and of the specimen to be tested, as well as the necessary controls and instrumentation to perform the test and to collect, record and manipulate data.

摘要： Provided are cone penetrometers for measuring the impedance of the ground. In an embodiment, the cone penetrometer comprises an inner electrode, an outer electrode, an insulator layer and a penetrating rod. The inner electrode includes a cone, a first contact portion to which terminal cables of an impedance meter are connected, and a metal rod. The metal rod has a diameter smaller than that of the cone. The metal rod has a front end connected to the bottom of the cone and a rear end connected to the first contact portion. The outer electrode has an inner diameter smaller than the diameter of the cone and is in the form of a hollow tube accommodating the metal rod. The insulator layer is formed between the inner electrode and the outer electrode to prevent short circuits between the two electrodes. The penetrating rod is in the form of a hollow tube accommodating the outer electrode. The use of the cone penetrometers improves the accuracy and reliability of the measured results. Further, the cone penetrometers can be miniaturized while maintaining high stiffness against buckling.

摘要： A device for detecting the depth of penetration of the tip of an indenter of a hardness tester has a terminal crown turnable and slantable with respect to a cylindrical body of a reference sleeve, terminating with two spikes extending from diametrically opposed positions of a circular end surface of the terminal crown, the vertexes of which bear on the surface of the piece to be tested. The terminal crown having an end retained within the body of the sleeve and an inner circular surface defining a cuspid along a diameter orthogonal to the diameter of alignment of said two spikes, abutting on a planar circular end surface of the retaining body of the sleeve such to determine a linear or fulcrum abutment along diametrically aligned vertexes of said cuspid. The tester uses an indenter of a hard metal or compound by periodically recalibrating a hardness tester in function of said depth of penetration originally established on a reference sample of known and homogenous hardness. A method of deriving a hardness profile in terms of Vickers points for a certain depth by using the hardness tester is also described.

A stopper assembly having a stopper tip on one end in contact with the test material or object, and a washer on the opposite end attached to a rod. A projectile is propelled with a selected level of force along the rod and impacts the washer, which transmits the force of impact through the stopper tip to the test material or object. The level of propelling force, the mass of the projectile, the construction of the stopper assembly and the location of impact on the test material or object may be precisely adjusted to simulate real-life impacts.

摘要： A ball penetrometer probe for in situ measurement of soft soil properties, particularly in the seabed, comprises a spherical body and slender shaft assembly, and either individually or in combination, an anti-friction sleeve enclosing the shaft and/or a peripheral porous ring on the spherical body with connecting internal passages through the shaft assembly, the shaft being adapted to attach to an electronic transducer module. The ball penetrometer is deployed to penetrate the soil bed, to continuously measure the soil bearing forces resisting penetration and withdrawal of the ball, to optionally measure the pore water pressure of the soil in contact with the ball and to transmit the measurement data from the probe to a remote operating station, either by wireless means such as an acoustic transducer or via a wired electrical connection.
