Algorithms remove material from low-stress regions to find lightweight structures.
Optimisation algorithms (SIMP) distribute material in a design domain to minimise compliance under a volume constraint. The result is organic, lightweight structure, often built by additive manufacturing. Needs manufacturability constraints.
Aircraft brackets reduced in mass by 30–50%.
Topology optimisation finds where material is needed, so it can produce lightweight parts that meet stiffness or strength goals.

An optimised distribution of material within a design space, often with organic shapes that must then be made manufacturable.
The raw result may be hard to manufacture or may depend on load cases that are not realistic, so engineers must simplify and check it.
Typical applications include generating a lightweight aircraft bracket that keeps its stiffness, finding the material layout of a 3D-printed hinge and creating an initial concept for a bracket that is then refined by hand.
Study "Finite element analysis in mechanics" first (topic 99 of 106 in Engineering Mechanics). It covers the groundwork this topic builds on.
Density-based method. Stiffness-to-weight maximised. Post-processing needed.
Aircraft brackets reduced in mass by 30–50%.
The next topic is "Lagrangian mechanics", which builds directly on this one.
It is classed as Advanced in Engineering Mechanics (topic 100 of 106). It is an advanced topic. It assumes you are comfortable with the intermediate topics in Engineering Mechanics.
