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?

Virtual Product Development capability is becoming an asset in many companies. A company’s ability to do virtual validation depends on CAE resources and an ability to do repeatable, reliable and robust CAE at all phases of product development. It is essential that a Governance System be put in place to take advantage of the virtual capability.
