Abstract

Internal strain/stresses in the nacre layer of mollusk shells are measured as a function of depth under controlled etching in selected areas. We found strain release to be enhanced when approaching the inner surface of the shell adjacent to the mollusk mantle. Strain distribution across the thickness of the shell consists of two components: a slowly changing component, which reflects elastic bending of the shell; and a short-range periodic modulation due to forces acting at interfaces between ceramic lamella. Simulations based on the multilayer structure model reproduce well the main features of the obtained experimental data.
