PartWorks products provide residual stress solutions for the fatigue and damage tolerance enhancement of fastened structure or single pinned joints. We work with customers to identify the critical product and process parameters to drive the design solution. This can include applied interference levels, minimum compression in the structure or not to exceed tensile stress limits. The designed configuration can be evaluated with analytical models, FEA, as well as experimental techniques including digital image correlation (DIC) and physical testing to ensure that the product and installation function as desired.

We are developing the world’s first high performance handheld cold expansion tool. Data collected from the tool can validate that the process was done correctly using parameters derived from our extensive fatigue test programs. This ensures that there is documentation that a specific hole was repaired, and repaired properly, which supports the case for life extension credit.
