A geometric approach for controlling local overheating in topology optimization for additive manufacturing

Additive manufacturing (AM) has revolutionized part manufacturing, offering unprecedented design freedom and the ability to fabricate intricate structures. Computational design methods like topology optimization (TO) effectively capitalize on AM's design freedom. However, manufacturability constraints must be considered to ensure reliable...

Validation and optimization of Patient-specific orthopedic plate design for proximal femur fixation in slipped capital femoral epiphysis patients

Slipped capital femoral epiphysis (SCFE) is a condition in adolescents affecting the proximal femur. Increased mechanical forces result in fracture of the growth plate. Factors increasing the mechanical forces include for example obesity and endocrine disorders. As a result of the fracture a shift of the bone shaft towards the femur head occurs,...

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...

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...

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...
