On the Assessment of Additive Manufacturing Potential in the Maritime Construction Sector: The Effect on Ship Design

Additive manufacturing, colloquially known as 3D printing, is a production process that offers possibilities compared to conventional production methods. Current methods involve shaping or removing of material to create parts, where additive manufacturing adds material. Several industries have successfully implemented the technology showing...

On the Assessment of the Potential of Topology Optimization: in the Maritime Construction Sector

Topology Optimization is an optimization problem based on the distribution of material within a design domain under specific load states. The goal of this technology is minimizing a certain function, such as compliance, mass or frequency. <br/>This technology can improve the performance of components in different fields within the shipbuilding...

Mechanical Metamaterials by Topology Optimization

Auxetic materials exhibit material properties, which are usually not seen in nature. This type of materials belong to the class of mechanical metamaterials and can be used for e.g. energy absorption, cloaking of objects, shape morphing applications and the design of fiber-reinforced composites. They exhibit a negative Poisson’s value and derive...

Topologically Optimised Cast Glass Shell: Topological optimisation and new fabrication methods for compressive free-form glass structures

Glass is a material which can be seen as a double-edged sword. Its monolithic, smooth, and transparent look transmits a sense of elegance and simplicity. However, due to its brittle mechanical property, it can create complex engineering challenges when intended for a structural load-bearing application. Many forget glass has a comparable...

Simulated Morphogenesis using Ghost Layer Optimization for Additive Manufacturing

Morphogenesis of living organisms could be used as inspiration to digitally augment the reinforcement of structures. The design space in terms of fiber orientation was enlarged to facilitate more complex patches with improved performance that can be 3D printed using a ghost ply optimisation. Simulations performed on optimized open-hole tensile...
