Control of Fine Cutting Chips to Improve the Processing Environment in CFRP Drilling
Autor: Junji Miyamoto, Kazushige Tokuno, Takashi Inoue, Masahiro Hagino, Takeshi Nishiwaki
Publikováno v: International Journal of Automation Technology. 15:466-474
Carbon fiber reinforced plastic (CFRP) is increasingly used in aerospace, automobile, and other industries. With the improvement of carbon fiber reinforced thermoplastic molding technology using thermoplastic resin, it is expected that the applicatio

Description of anisotropic properties of sheet metal based on spline curves and hole expansion test simulation of high-strength steel
Autor: Toshiro Amaishi, Takaaki Kimoto, Hideo Tsutamori, Takeshi Nishiwaki
Publikováno v: International Journal of Solids and Structures. 202:672-684
A plane stress yield function with a yield surface described by Bezier curves comprising arbitrary numbers of segments is presented. This yield function can consider an arbitrary number of multiaxial stress states and their plastic strain rate direct

A Plane Stress Yield Function Described by Multi-Segment Third Order Bézier Curves
Autor: Hideo Tsutamori, Takaaki Kimoto, Takeshi Nishiwaki, Toshiro Amaishi
Publikováno v: Key Engineering Materials. 794:163-168
A plane stress yield function which is described by multi-segment spline curve is proposed. This model is able to consider an arbitrary number of multi-axial stress states and its normal directions on the yield surface. Moreover by using interpolatio

Hydro-Mechanical Deep Drawing of Locally Solution-Treated Aluminum Alloy Sheets
Autor: Takeshi Nishiwaki, Hideo Tsutamori, Ryota Sako
Publikováno v: Forming the Future ISBN: 9783030753801
Improvement of formability of aluminum alloy sheets is desired because of their lower drawability than mild steel. Therefore, the special sheet forming methods such as a hydro-mechanical forming and a tailor heat treated blank have been developed for

Calibration and Validation of Stress–Strain Curve in High-Strain Region of Mild Steel Sheet
Autor: Hideo Tsutamori, Hiroaki Onishi, Takeshi Nishiwaki
Publikováno v: Forming the Future ISBN: 9783030753801
Stress–strain curve in the high-strain region is one of the most important models that must be taken into consideration for high-precision sheet metal forming simulation. In this study, using mild steel sheets, tensile tests were conducted with a n
