The tearing moduli for the 100 and and simulator studies to make a determination of the 200 kGy samples were negative in value, indicating that appropriate choice of UHMWPE for application in the toughness of UHMWPE for these doses was lower total knee prostheses. than the minimum material toughness required by the RiceSorensen model
ASTM D4533 - Trapezoid Tearing Strengths of Geotextiles - Specimens are 3 inches wide by 8 inches long and marked with an isosceles trapezoid. A preliminary 0.625 inch long cut is made on the specimen. The specimen is clamped along the marked trapezoid and then pulled in tension at a constant crosshead speed. The maximum force is recorded and reported as the tearing strength.

J-integral fracture toughness and tearing modulus J-integral fracture toughness and tearing modulus measurement of radiation cross-linked UHMWPE. December 2002; Journal of Orthopaedic Research 20(6):1152-6; DOI:10.1016/S0736-0266(02)00073-6.
L&W Autoline Tear Automated tearing strength L&W Autoline Tear measures the tearing strength of paper in the machine and the cross directions. This simultaneous measurement enables fast, detailed feedback to production. The Autoline Tear method was developed in 1995 by Lorentzen & Wettre, and has become the de facto standard (ISO 18 522) for automated tear strength testing. The values obtained can also be recalculated to Elmendorf-method
B. TEAR TEST. Geotextiles use the trapezoidal tear test (ASTM D4533) which reports values in pounds of force (lbs converts to N). C. PUNCTURE TEST. Geotextiles use the ASTM D4833 Puncture test with values reported in pounds of force (lbs converts to N). D. BURST TESTS. Geotextile burst tests measure the pressure required to burst a Textile on a
On the tear resistance of skin Nature CommunicationsMar 27, 2015 · Tear resistance is of vital importance in the various functions of skin, especially protection from predatorial attack. Here, we mechanistically quantify the extreme tear resistance of skin and
Tearing Strength - an overview ScienceDirect TopicsTearing strength. A fabric tears when it is snagged by a sharp object and the immediate small puncture is converted into a long rip by what may be a very small extra effort. It is the most common type of strength failure of fabrics in end use. For garment items, such as outdoor clothing, overalls and uniforms, the tearing strength is a very important quantity. The fabric tear property measured is the force required to propagate an existing tear and not the force required to initiate a tear
Tearing Strength Tester is a consistent tool useful to determine the tearing strength of fabrics, plastic films, and similar materials. Tearing Strength Tester is the tensile force required to rupture a pre-slit sample under controlled test conditions.
Textile & Fabric Testing Equipment - Friction, Tearing ASTM D5587 Standard Test Method for Tearing Strength of Fabrics by Trapezoid Procedure TQD-G1 Air Permeability Tester TQD-G1 is professionally applicable to the determination of air permeability of decorating materials used in cars, e.g. polyurethane, expanded plastics, PVC, leather, textiles, non-woven and other materials.
The measurement of mode I dynamic shear crack resistance Jan 01, 1993 · An experimental technique has been developed to measure the dynamic shear crack propagation resistance of structural steels. The test consists of a Double Cantilever Beam (DCB) specimen being loaded via pins in a high rate servohydraulic machine at crosshead displacement rates of up to 5.97 m s 1.The specimens were side grooved to control direction of crack propagation and to
