Description of Multi-Functional Crack Growth Rate Testing Machine , Stress Corrosion Crack , Crack Growth Rate

Multi-functional crack growth rate testing machine is used in the corrosive medium environment for measuring the slow strain rate tensile, corrosion fatigue loading and crack growth length. The crack growth measurement uses DCPD method, and can apply in the corrosive medium environment. According to the connected corrosive medium environment to configure the suitable experiment caldron in order to satisfy the specific testing requirement.

The host machine structure is adopted frame type; the loading unit can upside down and fixes in order to meet the different medium environments testing requirement.

Feature of Multi-Functional Crack Growth Rate Testing Machine , Stress Corrosion Crack , Crack Growth Rate
