Description
The advancements in additive manufacturing have made it possible to bring life to designs
that would otherwise exist only on paper. An excellent example of such designs
are the Triply Periodic Minimal Surface (TPMS) structures like Schwarz D, Schwarz
P, Gyroid, etc. These structures are self-sustaining, i.e. they require minimal supports
or no supports at all when 3D printed. These structures exist in stable form in
nature, like butterfly wings are made of Gyroids. Automotive and aerospace industry
have a growing demand for strong and light structures, which can be solved using
TPMS models. In this research we will try and understand some of the properties of
these Triply Periodic Minimal Surface (TPMS) structures and see how they perform
in comparison to the conventional models. The research was concentrated on the
mechanical, thermal and fluid flow properties of the Schwarz D, Gyroid and Spherical
Gyroid Triply Periodic Minimal Surface (TPMS) models in particular, other Triply
Periodic Minimal Surface (TPMS) models were not considered. A detailed finite
element analysis was performed on the mechanical and thermal properties using ANSYS
19.2 and the flow properties were analyzed using ANSYS Fluent under different
conditions.

Description
Traumatic brain injuries and the effects they can bring are becoming the main focus among researchers and physicians. Cycling is the leading sport with the most traumatic brain injuries, but the design of the cycling helmet has stayed the same for decades now. The technology of a bike is constantly getting developed and testing but the helmet is lagging behind. This project consists of designing and testing different cycling helmets through ANSYS simulations to determine the ideal geometry and features a cycling helmet must include, reducing the stress that the head experiences upon impact during a fall.
