“…Nasiri et al conducted repeated underwater explosive forming tests with 3 mm thick Armco ® iron plates, and 12 g and 4 g PE4 explosive charges were used for single and repeated loading, respectively. According to the experimental and simulated results, smoother thickness distribution and higher formability were obtained with repeated explosive forming [67]. Therefore, it can be concluded that repeated loadings at high strain rates can effectively increase Electrohydraulic forming (EHF) was developed in the 1960s [59]; the forming force of sheet deformation was obtained from the instant release of electrical discharge inside the liquid chamber [60][61][62].…”

Titanium alloy sheets present inferior formability and severe springback in conventional forming processes at room temperature which greatly restrict their applications in complex-shaped components. In this paper, deformation characteristics and formability and springback behaviors of titanium alloy sheet at room temperature are systematically reviewed. Firstly, deformation characteristics of titanium alloys at room temperature are discussed, and formability improvement under high-rate forming and other methods are summarized, especially the impacting hydroforming developed by us. Then, the main advances in springback prediction and control are outlined, including the advanced constitutive models as well as the optimization of processing paths and parameters. More importantly, notable springback reduction is observed with high strain rate forming methods. Finally, potential investigation prospects for the precise forming of titanium alloy sheet in the future are suggested.

It is known that products made of polymer materials or especially polymer materials with glass fiber and carbon fiber are used in many different areas such as automotive, aerospace, and defense. At this point, studies in the literature have gained momentum due to the combination of fiber-reinforced polymer materials emerging as a result of technological developments and industrial demands, and the fused deposition modeling (FDM) method providing the production of parts in desired sizes and complexity. Residual stresses and distortions occurring in polymer-based composite parts produced with FDM are among the problems that should be minimized. In this study, the influences of fiber ratio (%10, %15, and %20), infill rate (%20, %50, and %80), and infill pattern (line, honeycomb, and triangle) on the residual stresses and warpages generating in impact test specimens produced from glass fiber reinforced ABS filaments by fused deposition modeling were tried to be determined with the Digimat 2021 program. As a result of the findings, it was determined that the distortion values decreased and the thermal residual stress values went up with the increase in fiber ratio and infill rate. In addition, it can be reported that the distortions that bring out as a result of the separation of the produced parts from the production platform are caused by the high deformations condensing at the lower corner points of the parts.
