The wide application of advanced high strength steels with specific in the automotive industry can significantly reduce energy consumption and contribute to carbon neutrality. Accurate prediction ductile fracture behavior under complex stress states is great significance for its automobile industry. In this study, QP980 states, covering shear, uniaxial tension, plane strain investigated by cond...

Advanced polymer matrix composites are gaining the market in their way due to exceptional specific stiffness, strength, fatigue, and corrosion resistance field of Auto-Tech, Aero-Tech, Biotech, etc. However, lack ductility catastrophic failure has limited application these areas. Hence there is a need explore means protocols for designing reduced factor safety with high-performance toughened co...

While a freestanding high-strength sheet metal subject to tension will rupture at a small strain, it is anticipated that lamination with a ductile sheet metal will retard this instability to an extent that depends on the relative thickness, the relative stiffness, and the hardening exponent of the ductile sheet. This paper presents an analytical study for the deformability of such laminate with...

The effect of chain packing on tensile properties was studied employing amorphous poly(lactic acid) PLA. It was found that the samples cooled in the temperature range from 60 to 80 °C, that is, slightly higher than the glass transition temperature Tg, showed ductile behavior with a low brittle-ductile transition temperature. Furthermore, the samples obtained by prolonged cooling at 56 °C also s...

This paper introduces a finite element scheme and a systematic calibration approach for masonry infilled RC frames. The modeling scheme combines the smeared crack approach with discrete crack elements to allow for the opening of diffused flexural and dominant shear cracks. It is, therefore, able to capture the nonlinear material behavior and the interaction of the infill wall with the bounding ...

The use of self-tapping screws with continuous threads as a reinforcement to avoid splitting of members in connections with dowel-type fasteners was studied in two projects carried out at the Universities of Nottingham and Karlsruhe. The reinforced specimens showed a very ductile failure mode whereas the non-reinforced specimens failed in a brittle way. Although the reinforced specimens also sh...
