Are machining-induced residual stresses causing unacceptable distortion? Need to simulate the influence of cold working sequence for a given hole pattern? Residual stresses (RS) can have a significant impact on the strength, durability and damage tolerance of metallic and composite parts. In the past, reliably simulating RS effects was challenging due to extreme stress gradients, especially in lightweight components.
Residual Stress Applications
With the technology in StressCheck, representing rapidly changing stresses over short distances is a breeze.
RS effects can be beneficial, such as life extension by cold working one or more fastener holes, or detrimental, such as distortion leading to expensive re-working or rejection of large, lightweight manufactured parts. Are you in good shape?

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
