Our diverse professional staff partners with the client to develop sampling and analytical procedures to identify and solve unique materials problems. Specializing in root-cause failure and product liability analysis, we determine how and why materials fail and provide practical solutions.
| Fatigue Testing |
Low-Cycle Fatigue Testing. RJ Lee Group has developed a method of automating the mapping of the circumferential surface within the gage section of low-cycle fatigue test bars in a scanning electron microscope. The mapping is completed before the bars are stressed so that surface inclusions can be tracked throughout the life of the bar. Inclusion crack lengths and growth are tracked in a database. The end result is a prediction model for determining the finite life of stressed parts in real-life applications. This procedure can also be applied to all other materials such as plastics, steel bars, and ceramics. |
