The single-lap or tensile shear test, despite all its obvious weaknesses, is the most widely used method for producing in-situ shear strength data for adhesively bonded joints. It provides a good indicator of the resistance to tensile shear stresses of bonded systems and is widely used for assessing chemical and fatigue resistance of adhesives.

Single Shear Test: This is the most straightforward type of shear test where a uniaxial force is applied until the material shears or fails. It’s typically used for materials like metal rods or bolts.

2021年1月15日 · The single-lap shear test is a widely used method to measure the performance of adhesives and surface treatments. A significant challenge with this method is acquiring consistent and reliable engineering data due to complex stress states caused by the sample geometry and loading condition.

Shear testing applies a lateral shear force to the specimen until failure results. Fasteners, such as bolts, may be pulled in single or double shear to SAE or ASTM specification. A single shear test fixture uses two blades with centrally located transverse holes.

In order to evaluate mechanical properties, single-lap shear experiments performed in prior studies at UCF were modeled utilizing finite element analysis (FEA). The tests were performed according to the American Society of Testing and Materials (ASTM) standards and follow the ASTM standard D1002 for single-lap shear testing under tension loading.

2024年8月27日 · Depending on the setup and purpose, different shear strength test methods can be performed, such as single shear, where the force is applied to one plane, or double shear, where the material is tested along two planes.

Single-shear, double-shear, and bending tests are all pull-off tests on adhesive joints which are pulled at the end of FRP to cause debonding failure. ... ... record the strains on FRPs, a...

Mesoscopic Simulation of FRP-Concrete Single Shear Test Considering Roughness [J]. Chinese Quarterly of Mechanics, 2024, 45 (1). doi: 10.15959/j.cnki.0254-0053.2024.01.005. 1. 2. 3.

2011年2月1日 · This article introduces a single lap shear test for the characterization of the composite-to-concrete or composite-to-steel bonded assemblies. In the first part, an extensive description of the test set-up is given and various methods are proposed to analyse the experimental results.

2023年8月14日 · Based on the lacking literature, the present work aims at modeling numerically a single-lap shear bond test by validating the model against existing predictions from the literature. To this end, we apply a cohesive zone model (CZM), as implemented in a classical finite element code, in order to investigate the crack initiation and propagation ...
