Finite elementsSheared edge Damage Viscoplasticity a b s t r a c t The capabilities of finite elements codes allow now accurate simulations of blanking processes when appropriate materials modelling are used. Over the last decade, numerous numerical studies have focused on the influence of process parameters such as punch-die clearance, tools geometry and friction on blanking force and blank profile (sheared edge). The proposed study focuses on the finite elements simulations of a blanking process using a new viscoplastic model for the evolution of the flow stress coupled with a new damage model. The commercial finite elements code ABAQUS/Explicit has been chosen to simulate the blanking process. The finite elements predictions have been compared with experimental results. Then the finite elements simulations have been used to assess the influence of punch-die clearance as well as the influence of tool wear and friction on sheared edge quality.

Thermal reactions of bauxite, kaolin, and talc compound were investigated at 1550°C to obtain high rigidity ceramic for ballistic applications. The compressed strength and density of the bauxite ceramics with kaolin and talc substitutions varied from 195 to 455 MPa and density from 2.85 to 4.05 g/cm 3 . The Young's modulus varied from 107 GPa to 222 GPa with water absorption varying from 1.4 wt% to 5.9 wt% for 0 wt% and 15 wt% substitution of kaolin. The substitution of bauxite-kaolin by talc up to 7.5 wt% contributes to the resorption of microporosity and increase the Young's modulus from 107 to 195 GPa. The XRD of bauxite ceramic with kaolin substitution showed the presence of corundum and mullite; whereas the XRD of bauxite ceramic with kaolin and talc substitution showed the presence of corundum, mullite, and spinel. The ballistic simulation with abaqus dassult SIMULA using the JH-2 model predict that an impact with velocity of 525 to 810 m/s on the 10 mm thick bauxite ceramic does not erode or damage for a projectile consisting of tungsten alloy with dimensions: 12 mm in diameter, 61.5 mm length, and 72 g of mass. The bauxite ceramics can be used for ballistic applications. K E Y W O R D Sballistic application, bauxite ceramic, Young's modulus 950 |

Facing the forming requirements of large-sized automotive titanium bipolar plates (BPPs), a uniform pressure electromagnetic incremental forming (UP-EMIF) process was utilized. Corresponding simulation and analysis were conducted based on the designed arc spiral coil. Analysis of the magnetic field revealed that during the forming process, electromagnetic forces on the coil wire tended to compress in radial direction, while the electromagnetic forces on the outer channel exhibited repulsive tendencies toward the driver sheet, and the electromagnetic forces on the driver sheet transitioned from a wavy pattern to a uniform distribution. Velocity and equivalent strain analysis showed that the maximum deformation velocity of the blank occurred at the bottom of the channel, reaching 195m/s. The highest equivalent strain of the blank occurred in the rounded corner R region, which was prone to thinning of wall thickness. Based on these findings, UP-EMIF and traditional quasi-static drive rubber pad forming (QS-DRPF) experimental devices were developed, and a comparative study on the forming of 0.1mm thick automotive titanium BPPs was conducted. Research indicated that successful production of a titanium BPP measuring 485mm×195mm was achieved using three consecutive discharges of 9kV in each discharge region under the discharge capacitor of 100μF, an acceleration distance of 2mm, a coil overlap rate of 15%, and a 0.3mm thick Cu110 driver sheet. The depth of the channels was 0.4mm (channel depth-to-width ratio of 0.53). Compared to traditional QS-DRPF, the 9kV UP-EMIF reduced channel thinning effectively, with a maximum thinning rate of 18.2%, while simultaneously improving channel filling, with a maximum filling rate of 96.3%. This demonstrates the feasibility of UP-EMIF as a process for fabricating automotive titanium BPPs.
