Residual Stress Applications

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.

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?

With the technology in StressCheck, representing rapidly changing stresses over short distances is a breeze.

Residual Stress Application Focus

The following are typical residual stress analysis applications which are routinely performed in StressCheck Professional:

StressCheck® Core
Linear Elasticity Solver
Non-Linear Solver
Cold Working Solver

View Case Studies

Applicable Products:

Representing cold working processes is a must for any structural integrity engineer: mandrel insertion, removal and subsequent reloading/unloading of holes to evaluate residual stress states. Users can also trace the residual stress history for each step.

Cold Working Residual Stress (RS) Analysis

StressCheck® Core
Linear Elasticity Solver
Bulk Residual Stress (BRS) Module
Subsurface Residual Stress (SRS) Module

View Case Studies

Applicable Products:

Specify RS distribution throughout a part, or on surfaces of a part, and compute distortion after multi-step machining or due to surface treatments (e.g. shot peening). Seamlessly account for redistribution of RS after material is removed.

Machining Distortion & Residual Stress (RS) Redistribution Analysis

StressCheck® Core
Linear Elasticity Solver
Fracture Mechanics Module
MeshSim Advanced Automesher
Bulk Residual Stress (BRS) Module
Subsurface Residual Stress (SRS) Module

View Case Studies

Applicable Products:

RS can have a significant impact on crack behavior, so we compute fracture mechanics parameters accounting for the full part RS distribution (if available) or the partial RS distribution at the crack face. Predict the influence of cold working RS on cracks.

Testimonials

“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.”
