Effects of the use of modern CAE tools on the design process: Case: Design, strength calculation and optimization of a gantry on a trailing suction hopper dredger vessel

Over the years the introduction of new Computer Aided Engineering (CAE) software into the design process allowed engineers to significantly shorten the time necessary to produce finished designs. There seems to be an agreement that using CAE tools shortens the time of the design process and improves the quality of finished products. Although,...

Multi-material 3D printed mechanical metamaterials: Rational design of elastic properties through spatial distribution of hard and soft phases

Up until recently, the rational design of mechanical metamaterials has usually involved devising geometrical arrangements of micro-architectures that deliver unusual properties on the macro-scale. A less explored route to rational design is spatially distributing materials with different properties within lattice structures to achieve the...
