Question

Why are ceramics typically much stronger in compression than in tension?

• A. Because they contain inherent micro-cracks that act as stress concentrators under tensile loads
• B. Because they have a high density of mobile dislocations
• C. Because their ionic bonds are only stable under compressive forces
• D. Because they undergo significant plastic deformation before fracture

Hint:

To prevent tensile failure in ceramic components:
1. Design parts to be loaded primarily in compression.
2. Minimize internal flaws by using advanced manufacturing methods (e.g., hot-isostatic pressing).
