Multi-Functional Crack Growth Rate Testing Machine

Product Description

Multi-Functional Crack Growth Rate Testing Machine , Stress Corrosion Crack , Crack Growth Rate 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 High rigid overloading framework.High performance digital servo load control system, the speed control accuracy is high.Can use double transformation sensor, specimens transformation measurement accuracy is high.Pressure-balanced system, can equip water cooling system.Integrated form measurement and control system, its convenient to extension.Can achieve crack growth measurement in the corrosive medium environment.
