When discussing residual stress measurements, few names are as influential as Mike Prime. A recognized expert in the behavior of metals under extreme conditions, Mike has made significant contributions to engineering, manufacturing, and materials science throughout his career.
After attending UC Berkeley where he studied under one of the leaders in the residual stress community, Ian Finnie, Mike Prime accepted a role at Los Alamos National Laboratory, where he developed the contour method in 1999, a groundbreaking technique for measuring residual stress in manufactured metal components. The contour method provides a full two-dimensional map of residual stress across a cut plane, giving engineers valuable insight into how manufacturing processes affect material performance. Today, the method is widely used across aerospace, defense, energy, transportation, and other industries around the world.
Mike’s invention also played a pivotal role in the history of Hill Engineering. Shortly after developing the contour method, he connected with fellow residual stress expert Mike Hill, and together they began advancing the technology at UC Davis in 2000. As the method matured for commercial applications, it revealed new opportunities to support emerging technologies such as laser peening.
Today, Hill Engineering continues to employ the contour method as one of its core residual stress measurement techniques. Mike Prime’s innovation remains a cornerstone of the industry and an important part of Hill Engineering’s foundation and success.
