Mechanical Properties and Structure of Haliotis Rufescens, Strombus Gigas, and Tridacna Gigas Sea Shells:
A Comparative Study
Conch: Toughening Mechanisms
Abalone: Toughening Mechanisms
Mechanical Analysis: Giant Clam
Hydration: Effect on the mechanical response of Giant Clam shell
The abalone shell has higher mechanical strength then conch and giant clam shells.
Over organization with 45 degree shear angles in micro structure of Conch shells results in under-optimized mechanical response in compression.
Structure shows impressive response in tension.
Compression : tension ratio of approx 4 (most ceramics have a ratio in the range of 10)
Growth rates, and continuous single growth crystals may attribute to less organization and strength in Giant Clam.
Hydration of shells with seawater, increased toughness over time.
