Abstract
A set of new computer aided system (CAS) programmed by C + + and developed on X86 series microcomputer for comprehensively measuring crack growth rate is briefly introduced and some part of algorithms for data process and the selection technique of load-variation are given. The CAS mentioned above can be applied to tests with different range of load ΔP and range of stress intensity factor ΔK such as constant ΔP method, constant △K method as well as decreasing ΔK and increasing ΔK method. Compared with other systems, the new systems can increase the measurement accuracy, shorten testing time and obtain more information. It has been successfully used in measuring corrosion fatigue crack growth rate, which shows that the system is effective in measurement and reliable in function.
