Punching shear in concrete slabs
International Journal of Mechanical Sciences, 1999Punching shear in concrete slabs is a serious problem in certain structural systems, such as flat slabs. Current analysis is based either on empirical and simplified analytical techniques or on theoretical models, mainly based on the theory of plasticity.

CFRP laminate as punching shear reinforcement
Engineering Structures, 2021Abstract Punching shear strength is one of the main parameters in the design of reinforced concrete flat slabs not only for the brittle nature of punching shear failure but also because such failure may affect the whole structure through progressive collapse.

Meniscal shear stress for punching.
Journal of applied biomaterials & biomechanics : JABB, 2009Experimental determination of the shear stress for punching meniscal tissue.Meniscectomy (surgical treatment of a lesion of one of the menisci) is the most frequently performed arthroscopic procedure. The performance of a meniscectomy is not optimal with the currently available instruments.

Punch shear strength of polycarboxylate cements
The Journal of Prosthetic Dentistry, 1978Two general conclusions are drawn which apply to all the four commercial polycarboxylate cements: First, the effect of storage condition upon shear strength was much more pronounced after 24 hours than after 1 hour of storage time; second, the effect of storage condition was most extreme when the specimens were tested free of their matrices ...

EFFECT OF SPECIMEN THICKNESS AND PUNCH DIAMETER IN SHEAR PUNCH TESTING
Canadian Metallurgical Quarterly, 2006AbstractA good method to directly measure the mechanical properties of a material deformed in compression or torsion is by using the shear punch test. Unlike tensile testing, the shear punch test is not limited by specimen size or shape. However, it is unclear whether there is a limit to the allowable specimen thickness and punch diameter in order to ...

Various slabs in reinforced concrete structures, such as flat floor slabs, spread footings, and pile caps (Fig. 1.4), may fail in the patterns shown in Fig. 9.1, under local compressions, which are perpendicular to the slabs and of high intensity.

Punching shear behaviour of shear reinforced concrete slabs
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2015This study investigates the punching shear behaviour of reinforced concrete slabs with various shear reinforcement, including newly developed metallic fibres. Six slab specimens of dimensions 1800 × 1800 × 120 mm are constructed. The test parameters include fibre type, shear reinforcement type and fibre volume fraction.

Punch-Shear Test for Dental Purposes
Journal of Dental Research, 1970Average shear stress may be calculated from the force required to punch a cylinder out of a disk or plate of material. Tests on aluminum and methacrylate sheets enabled the comparison of dental restoratives with human dentin. Human dentin was found to have a greater shear strength than dental restoratives other than gold alloys.
