The measurement accuracy of directrix, fault creep characteristic and the retrogressived movement are discussed with the analysis of the data.

The long-period events before earthquakes have been theoretically demonstrated by fault creep before earthquakes,silent and slow earthquakes,fracture pre-pro.

The creep rupture properties of a low Re content second-generation directionally solidified superalloy DZ59

If the creep rupture .

The interface carbon diffusion,mechanical properties of joints and thermal stress on the interface area have been investigated by means of creep rupture tests,EPMA analysis.

Forecasting of instability zones induced by creep fracture of tunnel rockmass;

Creep and creep fracture tests for the macro mechanical heterogeneous dissimilar steel welded joints fabricated by flash butt welding with high strength match (B M W H B L),low strength match (B H W L B M) and medium strength match (B L W M B H) were carried out respectively.

Analyses Ⅲ crack creep fracture under the influence of the initial co_linear array of microcracks antiplane using macrocrack_microcrack inteaction model and the theory of stress intensity factors for creep fracture,and presents the relation between the concrete antiplane Ⅲ crack stress intensity factors for creep fracture and the initial stress intensity factors was obtained.
