Factors affecting ultimate tensile strength and impact toughness of 3D printed parts using fractional factorial design

Amna Mazen et al.

Summary: This paper investigates the mechanical properties of specimens printed by 3D open-source printers, focusing on the effect of part orientation on ultimate tensile strength and impact toughness. The results show that both toughness response and tensile strength response are maximized with horizontal part orientation.

Hydraulic structures engineering: An evolving science in a changing world

Sebastien Erpicum et al.

Summary: Hydraulic structures are crucial for water management, but many are neglected and in poor condition. The engineering community should shift towards sustainability and embrace global perspectives. A new framework is proposed to strengthen links between academia and industry for more resilient water management.

Comparative Study of Nonsymmetrical Trapezoidal and Rectangular Piano Key Weirs with Varying Key Width Ratios

Xiaoyang Shen et al.

Summary: The study found that optimizing the key width ratio can significantly increase the discharge capacity of trapezoidal piano key weirs (TPKW), which are more efficient at high relative heads compared to rectangular PKWs. However, they are less efficient at low relative heads due to the shorter total crest length. The optimal key width ratio ranges are likely to be within 1.30 to 1.57 for TPKW and 1.50 to 1.77 for RPKW.
