Hill Engineering has developed and validated a computational design tool that predicts the residual stress and distortion caused by processes that provide compressive residual stress. This software, ERS-toolbox®, is the product of more than a decade of meticulous study and collaboration with government and private industry.
The flow chart illustrates how ERS-toolbox® complements OEM design and analysis information to provide estimates of performance benefits from a given residual stress treatment plan. This capability is a key for residual stress engineering of fatigue life extension processes, allowing virtual trials of treatment processes, process parameters, and processed area. These trials enable rapid and cost-effective design of residual stress treatments that meet customer goals.
