The Dynamic Behaviour of the Instrumented Charpy Test

The dynamic characteristics of the Charpy test have been studied by means OF a Hopkinson bar apparatus and photoelasticity. It is Found that this technique permits a clear evaluation of the test results, and is preferable to the standard instrumented pendulum test.

Ultimate tensile strength of tooth structures.

OBJECTIVE This study determined the ultimate tensile strength (UTS) of enamel (E), dentin (D) and dentin-enamel junction (DEJ) using the microtensile technique. It was hypothesized that the UTS of dental structures varies according to location and nature. METHODS Intact occlusal enamel surfaces from extracted human third molars were etched with 37% phosphoric acid and bonded with a one-bottle...

Experimental Assessment of the Equivalent Strain Rate for an Instrumented Charpy Test

Instrumented Charpy test data can be used to obtain estimates of dynamic yield strength, by means of a well-established relationship published by W. Server in 1978. A fundamental issue in comparing measured dynamic tensile properties and Charpy-based estimations is establishing the equivalent uniaxial strain rate for an instrumented Charpy test, typically conducted at ≈ 5.5 m/s. In this investi...

Ultimate Strength and Failure Mechanism of Resistance Spot Weld Subjected to Tensile, Shear, or Combined Tensile/Shear Loads

Strength tests were performed to reveal the failure mechanisms of spot weld in lap-shear and cross tension test samples. It is shown the while the lap-shear (cross tension) sample is subjected to shear (normal) load at the structural level the failure mechanism at the spot weld is tensile (shear) mode at the materials level. Based on the observed failure mechanism, stress distribution is assume...

Anomaly Detection for the Prediction of Ultimate Tensile Strength in Iron Casting Production

Mechanical properties are the attributes that measure the faculty of a metal to withstand several loads and tensions. In particular, ultimate tensile strength is the force a material can resist until it breaks. This property is one of the variables to control in the foundry process. The only way to examine this feature is to apply destructive inspections that make the casting invalid with the s...
