چکیده
To investigate and verify the degree to which forming properties of low plasticity materials are improved at room temperature using granular medium (GMF) process 500 °C, a coupled Eulerian–Lagrangian unit calculation model was established special mold designed conduct GMF experiment for titanium alloy sheets under different-shaped pressing blocks. Then, three-coordinate measuring machine, sizes outer contours parts formed were measured, results showed that bottom maintained smooth surface during drawing process. As height increased, radius curvature cambered gradually decreased. By wall thickness different positions from central axis caliper, distribution curves these obtained, deformations uniform uniformity good. comparing experimental data °C with traditional deep data, it found technology could improve plastic such as alloys.

The Effects of Forming Parameters on the Single Point Incremental Forming of 1050 Aluminum Alloy Sheet
The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...
متن کاملA Study on the Forming of Sheet Metal Parts Using Multi-Point Forming Technology
In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

In this study, the incremental forming of explosively welded low carbon steel-commercially pure titanium bilayer sheet has been experimentally and numerically investigated. For this purpose, at first a finite element based analysis was proposed to predict forming force and thickness distribution to form this material by such process, that showed good agreements with the experimental results.
