Abstract

This paper describes how finite element analyses were used to develop a method of in-situ determination of concrete material properties. A 3-D model of a concrete block with single hole under diametrical hydraulic jack force is idealised as a finite element model with 2308 nodes and 582 solid elements and is used as the prototype in this study. The strains, stresses and deformations of the block for nine possible combinations of Young's modulus E and Poisson's ratio v were used to determine the variation of strain at radial gauge locations. The relationship between strain and material property for the block with fixed geometry is investigated numerically, from which a fo
