... to block geometry and size (e.g. shape, change of shape, slenderness, fragmentation, etc.) when in site-specific applications are addressed. On the other hand, when the rockfall analysis is extended over large areas, simplified runout models can be used for preliminary, quick analyses, aimed...

... have shown in this study the importance of geometry of pillars by comparing calculations with and without the effect of W/H ratio (slenderness). The sensitivity of the parametric study based on the empirical relationships converges to the same resistance of the pillar despite the difference between...

... in uniaxial compressive stress tests, using prismatic and cylindrical specimens, considering their slenderness (respectively L/H and D/H), which Bieniawski (1984a,b) defines as the relationship between the smaller size of the section and its height. In order to quantify the influence of the rock mass...

... the specimen. The slenderness of the specimen and the conditions of contact between the specimen and the platens have a great influence on the apparent strength of rock cylinders (Hawkes and Mellor, 1970; Vukuturi et al, 1974; Paterson, 1978; Brady and Brown, 1985; Bridell, 1991; Labuz and Bridell, 1993...
