FepiM: A Novel Inverse Piecewise Method to Determine Isothermal Flow Curves for Hot Working

Metals, 2021
In forming simulations, flow curves are cardinal inputs to predict features, such as forming forces and material flow. The laboratory-scale experiments to determine them, like compression or tensile tests, are affected by deformation heating, restricting

Process-oriented Flow Curve Determination at Mechanical Joining

Procedia Manufacturing, 2020
Abstract The accuracy of numerical simulation models for forming processes depends highly on the method for the flow curve determination. Numerous experimental tests exist to identify the flow curves of sheet metals, each with certain characteristics regarding stress states and achievable strains. In this paper stress state analysis are presented for

Regularization Parameter Determination for Optical Flow Estimation using L-curve [PDF]

The KIPS Transactions:PartB, 2007
An L-curve corner detection method is proposed for the determination of the regularization parameter in optical flow estimation. The method locates the positive peak whose curvature difference from the just right-hand negative valley is the maximum in the curvature plot of the L-curve. while the existing curvature-method simply finds the maximum in the
