Strength Tests

In order to discuss on highly weathered metamorphic fillers as soft stone fillers，firstly the CBR tests for analysis on viability as embankment filler are conducted on three different highly weathered metamorphic fillers. Secondly the rock strength tests and particle broken tests are processed to study on how weathered degree and rock structure have an effect on them. Based on the above conclusions, evaluation criteria are proposed that have certain guidance and reference on mountainous highway construction.

Semiconductor Properties

The article presents results of strength tests of bismuth telluride prismatic samples obtained by growing crystals. These crystals have semiconductor properties and are used in the heat machines, the run-ability of which largely depends on the strength of crystals. Data available in the literature are significantly different from each other. It has been shown that, the most consistent strength tests results are obtained in case of bend testing. The measurement results of the elasticity modulus and tensile strength are given. For tests, an INSTRON testing machine with maximum direct stress of the 1000 H was used.
