In the past decades, many graph drawing techniques have been proposed for generating aesthetically pleasing layouts. However, it remains a challenging task since different layout methods tend to highlight characteristics of graphs. Recently, studies on deep-learning-based algorithms emerged but they are often not generalizable arbitrary graphs without retraining. this article, we propose Convol...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

Within the scope of this study, effects yield and hardening criteria used in forming simulations on part geometric dimensions were investigated. As material 0.8 mm thick DC04 is used. In results compared using Hill-48 Barlat-91 experimental flow curve, Hockett-Sherby, Ludwig Hollomon curve models. The studies carried out Simufact Sheet Metal Form software. Although all models studied because di...

Abstract In sheet metal forming simulations, the yield functions are usually calibrated based on experimental data, and validated by comparing modelled measured r-values (in more advanced models) stresses along various in-plane directions. The fitted function should ideally reproduce (or interpolate) all values used for fitting. However, this requirement does not guarantee accurate results in a...
