Residual Stress Applications

Home ApplicationsResidual Stress Applications

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.

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?

Residual Stress Application Focus

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

ColdWorkingAnalysis Cold Working Residual Stress (RS) Analysis 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. Applicable Products: StressCheck® Core
Linear Elasticity Solver
Non-Linear Solver
Cold Working Solver

BRSandSRSAnalysis Machining Distortion & Residual Stress (RS) Redistribution Analysis 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. Applicable Products: StressCheck® Core
Linear Elasticity Solver
Bulk Residual Stress (BRS) Module
Subsurface Residual Stress (SRS) Module

ResidualStressFractureAnalysis Residual Stress (RS) & Fracture Mechanics Analysis 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. Applicable Products: StressCheck® Core

Testimonials

  • When performing parametric structural analysis, ESRD’s p-element StressCheck® FEA software is always my preferred choice due to the excellent solution quality, parametric framework, and superior computational efficiency. In fact, I recently used StressCheck® to generate stress intensity factors along a parametrically defined elliptical crack-tip across 3,000 unique geometric configurations. Considering multi-body contact was present and all simulations were performed using a laptop, this was a task well suited for StressCheck®.
