Analiza porównawcza wytrzymałości rezydualnej powierzchni pozniszczeniowych na przykładzie wybranych struktur geometrycznych

Abstract

Comparative analysis of the residual strength of post-failure surfaces on the example of selected geometric structures.A b s t r a c t. The paper presents analysis of the residual strength and geometric structure (roughness) of post-failure surfaces of sandstones from Śmiłów and andesites from Wdżar Mountain. The analysis was carried out on the roughness of the surface distribution of samples obtained by extension and shearing tests of rocks. The morphology of these surfaces was characterized by statistical parameters and 2D and 3D maps, from investigations conducted using a Hommel Tester T8000 profilometer.
