摘要： A unitary test piece which dimensionally conforms with standardized dynamic tear testing guidelines comprises a middle section and two end sections welded thereto. The middle section is made of the test-subject metallic material. The two end sections are each made of a metallic material which is compatible with the test-subject metallic material, and primarily serve the purpose of combining with the middle section at its longitudinal ends in order to together form the dimensionally suitable test piece. The length of the middle section is at least the minimum such length that will totally encompass plastic deformation of such metallic material when subjected to dynamic tear testing, this depending on the nature of such metallic material. Ferrous end sections are compatible with a ferrous middle section; non-ferrous end sections of a particular designation are compatible with a non-ferrous middle section of the same designation. The invention advantageously permits economical utilization of test-subject metallic material under circumstances in which available samples thereof are expensive, limited, inappropriately or problematically sized, inappropriately or problematically configured, and/or intended to be tested for one or more properties in addition to dynamic tear.

摘要： A method of determining fracture mode transition behavior (FMTB) of solid materials by using stress field modified miniature specimens. The method is an improvement in the method of determining mechanical behavior information from specimens only so large as to have at least a volume or smallest dimension sufficient to satisfy continuum behavior in all directions. FMTB of the material is determined from the measurements taken during the loading of the specimen resulting in the formation of cracks and/or the further propagation of cracks in the miniature specimen and/or fracture. The specimens are provided with grooves that induce additional stress field modifying stress components in the specimens during the test. These additional stress components result in a desired stress state in the specimens which could not be achieved otherwise. The methods are useful in determining FMTB for the material, when the specimen thickness is smaller than previously thought necessary for valid FMTB determinations.

摘要： A method of determining the mechanical behavior of solid materials by using stress field modified miniature specimens. The method is an improvement in the method of determining mechanical behavior information from specimens only so large as to have at least a volume or smallest dimension sufficient to satisfy continuum behavior in all directions. Mechanical behavior of the material is determined from the measurements taken during the loading of the specimen resulting in the formation of cracks and/or the further propagation of cracks in the miniature specimen. The specimens include construction features for applying additional stress field modifying loads upon the specimens during the test. These additional loads result in a desired stress state in the specimen which could not be achieved otherwise. A particular example is the introduction of a transverse tensile load during a bend test to increase the transverse stress field to achieve plane strain conditions in a thin specimen. The methods are useful in determining plane strain fracture toughness, dynamic plane-strain crack initiation and arrest fracture toughness, the J-Integral for the material, and the fracture mode transition behavior when the specimen thickness and volume is smaller than previously thought necessary.

摘要： A fatigue test apparatus in which a specimen to be tested is attached at its ends to a pair of opposing pistons positioned within a pair of opposing cylinders. The cylinders are attached to a support frame such that the specimen is oriented substantially vertically. In a preferred embodiment, the specimen is enclosed in a heat chamber to test at high temperatures. Each of the pistons is attached to a shaft having a weight at its end and the weights are drivingly connected to a pair of shakers which are actuated to vibrate 180.degree. out of phase with each other. The cylinders are pressurized to exert a static tensile load on the specimen, and the shakers are actuated to exert a dynamic tensile load which is superimposed on the static load and travels through the weights, shafts and pistons to the specimen. With this arrangement, the dynamic load is not transmitted to the support frame so that the vibration characteristics of the support frame do not affect the vibration behavior of the specimen, yielding a dynamic load source independent of static or thermal load sources. more accurate results. By varying the magnitude of the weights and the stiffness characteristics of the shafts, static, dynamic or thermal fatigue tests may be conducted on a specimen either singlely or in any combination with dynamic loads imposed at frequencies as high as 10,000 Hz.
