“…The dependence of fracture behavior on stress growth rate is" therefore, of great research interest. Experiments on polycrystalline metals have shown that the stress growth rate has significant effects on yield strength [4,5], tensile strength [5,6], fracture toughness [7][8][9], crack tunneling [10], and crack growth speed [11]. Different from polycrystalline metals, nanocrystalline metals have a large grain boundary proportion.…”

Nanocrystalline metals have many applications in nanodevices, especially nanoscale electronics in aerospace. Their ability to resist fracture under impact produced by environmental stress is the main concern of nanodevice design. By carrying out molecular dynamics simulations under different fast loading rates, this work examines the effect of impact load on the fracture behavior of nanocrystalline bcc iron at an atomistic scale. The results show that a crack propagates with intergranular decohesion in nanocrystalline iron. With the increase in impact load, intergranular decohesion weakens, and plastic behaviors are generated by grain boundary activities. Also, the mechanism dominating plastic deformation changes from the atomic slip at the crack tip to obvious grain boundary activities. The grain boundary activities produced by the increase in impact load lead to an increase in the threshold energy for crack cleavage and enhance nanocrystalline bcc iron resistance to fracture. Nanocrystalline bcc iron can keep a high fracture ductility under a large impact load.

“…Hussaini et.al, [12] performed stretch forming of ASS 316 using a hemispherical punch for a temperature range from room temperature (RT) to 400 and plotted experimental FLD. They created an experimental forming limit diagram (FLD) and compared it to a theoretical FLD predicted using the Marciniak-Kuczynski model.…”

Sheet metal forming operations play a crucial role in the manufacturing process of various products. However, the challenge of plastic instability, which often leads to defective products, continues to persist in this field. It is important to consider various parameters, such as the Forming Limit Diagram (FLD), to overcome this issue during manufacturing. The Aluminium Alloy (AA2014) has been employed in this study to investigate its formability under different temperatures (room temperature, 150 °C, and 300 °C) at the strain rate of 0.1mm/s. The results of the study were obtained by performing stretch forming by utilizing the Nakajima test. The results showed the limiting strains of the material improved with an increase in temperature, and the findings were analyzed through fractography studies performed with a Scanning electron microscope, and simulations were done using LS-dyna software. This study provides valuable insights into the formability of AA 2014 sheets at elevated temperatures and will aid in the development of more efficient and effective sheet metal forming operations.
