CMS can perform tensile testing from 1 lbf to 160,000 lbf. CMS is an ISO/IEC 17025:2017 Accredited. . Wedge Tension Testing of Bolts—This testing process is to determine whether the bolt still meets the bolt's ultimate load requirements with the placement of a wedge under the bolt head. The wedge angle depends on the size of the bolt being . A wedge test was used to investigate the fracture locations of high-strength bolts with a tensile strength of 1600 MPa. Head separation occurred in the wedge tension test of a manufactured bolt with a corner fillet radius of 0.5 mm and a pitch size of 1.0 mm. This behavior is attributed to the fact that strength in the neck is low because of .TestResources manufactures and supplies universal test machines, tensile testers, dynamic testing machines, and much more. Call us today (800)430-6536. . These wedge grips are used for testing medium strength metal or plastic specimens. Max Force Capacity. 20 kN (4500 lbf) Max Opening. 13. Sample Diameter.
The types of fastener testing commonly performed at The LAB are yield strength, axial and wedge tensile, proof load, hardness testing, and magnetic permeability. Since many of the tests have already been described above, the focus in this section will be on axial and wedge tensile testing and proof load.Wedge Tensile. A Wedge tensile test is an axial test, except that a wedge is placed under the head during the testing. This wedge tensile test is typically done on hex or square head fastener and socket head cap screws. This test is to see if the head of the fastener is capable of sustaining the added stress of the wedge.

What is a tensile test?In the field of materials science and engineering, a tensile test is a widely used method to determine the mechanical properties of a material, specifically its response to tensile forces. It involves subjecting a specimen to an ever-increasing tensile load until it reaches its breaking point. By measuring the applied force and the resulting deformation .Is tested by means of having a wedge positioned underneath the screw head. When tensioned, the screw must break in the thread or in the shank. Bolts and screws are subjected to a wedge test to measure the ductility and head integrity.
In tensile testing, wedge grips are used on both ends of the specimen to position the specimen in the test frame. Wedge grips incorporate two main components: the grip body and two grip inserts, as seen in Fig. 1. .
Fig. 1: Typical Tensile Wedge Grip Inserts, for both flat and round test specimens. Wedge grip inserts of all types, in all sizes and load capacities to fit all existing wedge grip bodies, can be provided, including custom designs for . A 6.7 kN tensile tester is shown configured for an elastomeric tensile test. The sample is secured between two wedge-action grips. Force and travel distance are recorded and output to a PC for further analysis. . In tensile testing, a sample is subjected to a pull force. The test objectives vary from application to application, and can . Indirect tensile tests commonly used to measure concrete tensile strength include the Montevideo test (MVD) [6], the wedge splitting test (WST) [7], and the Double Edge Wedge Splitting (DEWS) test [8]. Among these tests, the DEWS test offers several advantages over the WST. . DEWS test is an indirect tensile test technique, in which a .

The self-intensifying clamping mechanism allows tightening the test specimen in between the wedge grip jaws at high forces. ADMET wedge grips are offered with the manual wedge action mechanism, pneumatic mechanism, a door knob, or with moving-body wedges. Moving-body wedge grips (GW527) should be used to avoid compressive loads on the samples.
Additional information on tensile grips and tensile testing: "Mechanical wedge grips for tensile testing," CompositesWorld, January 2009 "Additional grip types for tensile test specimens," CompositesWorld, February 2010 "Tensile testing composites: Simple concept, difficult in practice," CompositesWorld, January 2015These heavy duty self-tightening grips with a capacity range of 50 lbf to 2,000 lbF (250 N to 9 kN) are ideal for tensile testing of a wide range of materials. Select from rubber or serrated, hardened steel jaw faces. The jaws ride on rollers instead of sliding along the surface of the housing, as with conventional wedge grips. This unique design prevents jamming and . Wedge-splitting (WS) as shown in Fig. 1, proposed by Linsbauer and Tschegg [1], and Brühwiler and Wittmann [2], [3], is a convenient test method for heavy concrete specimens since the weight of heavy concrete specimen is supported.In comparison with a common notched three-point-bending (3-p-b) concrete beam, a WS specimen also has a relatively large un .
This compact self-tightening grip with a capacity of 100 lbF (500 N) is ideal for a range of low force tensile testing of small samples. The serrated steel jaws are easily opened with an ergonomic spring-loaded lever.
