Goal driven optimization of process parameters for maximum efficiency in laser bending of advanced high strength steels [PDF]
, 2015 Laser forming or bending is fast becoming an attractive option for the forming of advanced high strength steels (AHSS), due primarily to the reduced formability of AHSS when compared with conventional steels in traditional contact-based forming processes.

Accurate evaluation of a polynomial in Chebyshev form
Applied Mathematics and Computation, 2011 The authors propose a compensated Clenshaw algorithm to evaluate a polynomial in Chebyshev form, based on error-free transformations. Forward error bounds are established and numerical tests illustrate the efficiency of the new method for evaluating the polynomial in the neighborhood of a multiple root and near the ends of the standard interval.

Tool And Blank Interaction In The Cross-Die Forming Process [PDF]
, 2008 The deformation of the press and the forming tools during a deep drawing process is small. However, it has a significant influence on the formed product, since the draw-in is affected significantly by this deformation. This effect is demonstrated for the

Semigeostrophic Particle Motion and Exponentially Accurate Normal forms [PDF]
Multiscale Modeling & Simulation, 2006 We give an exponentially accurate normal form for a Lagrangian particle moving in a rotating shallow-water system in the semigeostrophic limit, which describes the motion in the region of an exponentially accurate slow manifold (a region of phase space for which dynamics on the fast scale are exponentially small in the Rossby number).

The influence of process parameters on the temperature development in the forming zone [PDF]
MATEC Web of Conferences, 2018 Cold metal forming is a fast and economical way of producing a wide range of precise components. Its profitability mainly depends on part quality, process stability and service intervals of tools.

Accurate closed-form solution of the SIR epidemic model
Physica D: Nonlinear Phenomena, 2020 An accurate closed-form solution is obtained to the SIR Epidemic Model through the use of Asymptotic Approximants (Barlow et. al, 2017, Q. Jl Mech. Appl. Math, 70 (1), 21-48). The solution is created by analytically continuing the divergent power series solution such that it matches the long-time asymptotic behavior of the epidemic model.

The Effect of Tool Path Strategy on Twist Behavior In Single Point Incremental Sheet Metal Forming
Journal of Engineering, 2023 In Incremental sheet metal forming process, one important step is to produce tool path, an accurate tool path is one of the main challenge of incremental sheet metal forming process. Various factors should be considered prior to generation of the tool
