Určování aktuální polohy trhliny pomocí metody digitální obrazové korelace
 Jandejsek, Ivan ; Vavřík, Daniel
This paper presents utilization of Digital Image Correlation and other image processing methods in determination of the actual position of the crack during the crack propagation in ductile material. This task is very important in fracture mechanics studies, especially in evaluation of full-field stress and strain in the vicinity of the crack. It encompasses detection of the crack faces, tracing of the crack tip and measuring the crack length.

Porovnání deformační a přírustkové teorie plasticity používané pro problémy experimetnální mechaniky
 Vavřík, Daniel
Deformation Theory of Plasticity is often used for evaluation of the experimental data. Main reason of this theory using is its simple implementation into experimental-numeric software. It is supposed that difference between power low and appropriate incremental theory applied is negligible if monotonic loading is presented and isotropic material is used. It is shown in this paper that this presupposition can be no longer valid if high ductile material is used although external loading is strictly monotonic and proportional.

Je logaritmická časová derivace jednoduše Zarembova-Jaumannova derivace?
 Fiala, Zdeněk
The paper raises a question whether the logarithmic time derivative, expressed in specific coordinate system, is the Zaremba-Jaumann time derivative, and if not why. In fact, it has been already proved that the Z-J derivative represents the geometrically consistent linearization of tensor fields along deformation process in terms of the covariant derivative in the space of right Cauchy-Green deformation tensors C.
