Ceramic bonding and structure and why it makes ceramics hard and brittle, traditional vs. advanced engineering ceramics, ceramic mechanical behavior, and applications in thermal/electrical insulation, cutting tools, and biomedical implants.
Ceramics take the ionic and covalent bonding introduced back in Module 1 and show exactly what those bond types do to a material's mechanical behavior when there is no metallic-bonding dislocation mechanism available to fall back on. This module builds the bonding-to-brittleness reasoning from first principles: why ceramics are so hard, why they fail from flaws rather than a bulk yield point, and why that flaw-driven failure mode forces a fundamentally statistical approach to ceramic strength that Module 3's deterministic metal yield strength never required.
By the end of this module you should be able to explain why ceramics are tested in flexure rather than direct tension, and why a ceramic component is deliberately designed to stay in compression wherever possible — reasoning that Module 12's fracture mechanics content and Module 13's failure analysis content both build on directly when a real ceramic or brittle component has actually failed in the field.
