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
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?

“At DST Group, we have effectively used StressCheck over the last 10 years to determine accurate stress intensity factors. The results have been used to improve our residual strength and structural life estimates for aircraft in service with the Royal Australian Airforce, including C-130, P-3C and F/A-18 A/B. We have found it to be extremely easy to use and a very versatile code with which to create parametric models.
We have recently used StressCheck to obtain improved stress intensity factor solutions (Improved stress intensity factors for selected configurations in cracked plates and Improved stress intensity factors for a single corner crack at a loaded fastener hole) for five key generic configurations. These transferable parametric results have been published externally. One specific example is the non-linear contact analysis of a cracked, filled fastener hole, with both fastener and remote plate loading.”
