Tricky subsurface residual stresses due to machining distorting your part? 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. Distortion caused by residual stresses poses difficult problems in manufacturing of large, lightweight components.
The effects of residual stresses can be beneficial, as in life extension by cold working, or detrimental, requiring reworking or rejecting manufactured parts. Reliably simulating effects of residual stresses is challenging due to extreme stress gradients. With the technology in StressCheck, representing rapidly changing stresses over short distances is a breeze.
