Worked Example

Verified calculation

Given:

Residual stress in X-direction = 100000000
Residual stress in Y-direction = 100000000
Residual stress in Z-direction (build direction) = 100000000
Reference stress magnitude = 100000000

Expected Result:

Residual stress anisotropy index = 0

Engineering Interpretation:

Under the given input conditions, the calculated result is: Residual stress anisotropy index = 0 dimensionless.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

residual stress anisotropy index = sqrt(pow((build direction - (residual stress in x-direction + residual stress in y-direction) / 2.0) / reference stress magnitude, 2) + pow((residual stress in x-direction - residual stress in y-direction) / reference stress magnitude, 2))
