โœฆ Synopsis

the graphite single crystal. The compliance constants ~11 and sb4 were determined by resonant bar and compound torsional-oscillator techniques, The stiffness constants cl 1, cia, css, and c44 were determined by an ultrasonic pulse method. All five compliance constants and their associated stressstrain curves have been measured by static tensile, compressive and torsion tests; fracture strength values were also obtained. In addition, a simple shear test gave the shear strength associated with c44 as a function of normal stress. Complications in testing procedures caused by the extreme anisotropy of the material will be discussed.

An investigation of the effect of specimen geometry on the tensile strengths of two nuclear graphites using seven different tensile specimen shapes has been conducted. The design of some samples gave rise to stress concentrations where the fillet met the gage section. Evidence has been obtained that

## Abstract We investigate the effect of specimen geometry on the ultimate tensile strength of cortical bone measured by a tensile test. This article is motivated by the fact that there is no clear consensus in the literature on a suitable specimen shape for cortical bone testing. We consider three

This paper analyses the shape effect on the tensile strength of axisymmetric rock specimens by an improved adaptive dynamic relaxation method. It is shown that the present approach is convenient and &cient. Numerical results for spheroidal specimens with different shapes reveal the variation of stre
