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.

The punch-shear strength of six cavity liners
Dental Materials, 1987Abstract The punch-shear strengths of 6 cavity liners, 5 based on calcium hydroxide and one on zinc oxide-eugenol, have been studied as a function of thickness and exposure time to a 100% rH atmosphere for periods of up to 7 days. The punch-shear strength of the ZOE material was found to be lower than that of the Ca(OH) 2 -based materials under ...

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.

The Crack Sliding Model – Unified Approach to Shear and Punching Shear
IABSE Congress, Chicago 2008: Creating and Renewing Urban Structures – Tall Buildings, Bridges and Infrastructure, 2008<p>This paper presents a unified mechanical model – The Crack Sliding Model - which can be used to calculate the shear strength as well as the punching shear strength of reinforced concrete structures. The model is based on the upper bound plasticity theorem. Contrary to the classical plasticity models to shear problems, the present model makes a
