Testing of mechanical properties of natural stones used as a building material
 Hasníková, Hana
Further presentation of some destructive and non-destructive methods for investigation of mechanical properties of natural stone quarried and used as a building material in Bohemia in the past is the aim of the paper.

Time-discrete integration of finite deformations
 Fiala, Zdeněk
Some necessary implications for the time discrete integration of finite deformations will be discussed together with particular Runge--Kutta--Munthe-Kaas schemes, when the geometrical structure of the space of Cauchy-Green deformation tensors, implicitly contained in the principle of virtual power, is taken into account.

Influence of geometric parameters on the stiffness of traditional dovetail timber joint
 Kunecký, Jiří ; Cacciotti, Riccardo ; Kloiber, Michal
The paper presents the development of numerical modeling for a traditional dovetail timber joint. The objective is to find the influence of its geometrical properties on the mechanical stiffness of the joint as well as to assess the main problems and limitations faced during the numerical modeling of the structure. An experiment with a replicated timber joint was used to validate the model. Material properties were ascertained and contact adjustment was made. Parametric study was performed: two angles of the joint beams were varied. Suitable ranges of the angles for each type of loading were found. Main limitations and problems present in the modeling are depicted in the discussion.

Determination of burst pressure of thin-walled pressure vessels
 Gajdoš, Lubomír ; Šperl, Martin
A simple fracture-mechanics based method is described for assesing a part-through crack in the wall of a pipe subjected to internal pressure of liquid and/or gas.
