Elemental analyses reveal distinct mineralization patterns in radular teeth of various molluscan taxa

W Krings, JO Brütt, SN Gorb - Scientific Reports, 2022 - nature.com
The molluscan phylum is the second specious animal group with its taxa feeding on a
variety of food sources. This is enabled by the radula, a chitinous membrane with embedded …

Micro-cracks and micro-fractures reveal radular tooth architecture and its functional significance in the paludomid gastropod Lavigeria grandis

W Krings, JO Brütt, SN Gorb - … Transactions of the …, 2022 - royalsocietypublishing.org

Material gradients in gastropod radulae and their biomechanical significance: a combined approach on the paludomid Lavigeria grandis

W Krings, Y Matsumura, JO Brütt, SN Gorb - The Science of Nature, 2022 - Springer
The radula, a chitinous membrane spiked with teeth, is the molluscan autapomorphy for the
gathering and processing of food. The teeth, as actual interfaces between the organism and …

Influence of water content on mechanical behaviour of gastropod taenioglossan radulae

W Krings, A Kovalev, SN Gorb - Proceedings of the …, 2021 - royalsocietypublishing.org

time, the performance and failure of taenioglossan radular teeth were tested in a …

Finite element analysis of individual taenioglossan radular teeth (Mollusca)

W Krings, J Marcé-Nogué, H Karabacak, M Glaubrecht… - Acta Biomaterialia, 2020 - Elsevier
Molluscs are a highly successful group of invertebrates characterised by a specialised
feeding organ called the radula. The diversity of this structure is associated with distinct …

Mechanical property gradients of taenioglossan radular teeth are associated with specific function and ecological niche in Paludomidae (Gastropoda: Mollusca)

SN Gorb, W Krings - Acta Biomaterialia, 2021 - Elsevier
Biological tissues may exhibit graded heterogeneities in structure and mechanical
