The mechanical properties testing, microstructure observation and fractographic features analysis of the troostite high chromium cast iron blade were carried out.

The results showed that the main reason of rupture is troostite structure existing in rod.

This paper is devoted to researching on the suits with focuses on pattern correcting experiments of the backward bending figure.

In order to connect different components of the imperfections with structural features and their effect on shell buckling strength, the imperfections are generally decomposed using Fourier series.

In this paper numerical simulation was used on investigating the matrix yielding initiation and expansion of polymer blends which has a continuous single phase and a regular particles shape.
