Detailed Product Description

 

YYF-50 Multi-Functional Crack Growth Rate Testing Machine , Stress Corrosion Crack , Crack Growth Rate

 

 

Equipment Introduction

 

  • Multi-functional crack growth rate (CGR) 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 environment’s testing requirement.

 

 

Equipment feature

 

  • High rigid overloading framework.
  • High performance digital servo load control system, the speed control accuracy is high.
  • Can use double transformation sensor, specimen’s transformation measurement accuracy is high.
  • Pressure-balanced system, can equip water cooling system.
  • Integrated form AEC-1800 measurement and control system, it’s convenient to extension.
  • Can achieve crack growth measurement in the corrosive medium environment.

 

 

DCPD crack growth measurement system

 

  • In the process of test, it used direct constant potential drop (DCPD) to dynamic detect the crack initiation and growth process; it can get the curve a/W-Time.
  • It can test CT (compact tension) specimen, and it usually uses 0.5T and 1T CT.
  • Crack growth resolution can be reached 1µm (decided by growth rate curve), and the absolute resolution can be 20µm.
  • Can be constant K control, and automatically adjust the middle value and R value in the loading force.
  • By the step of programming the constant L control, you can direct detect the fracture toughness property K1C of material.
  • Professional crack growth test software.
