The Armored Carapace of the Boxfish

Acta Biomaterialia, 2015
The boxfish (Lactoria cornuta) has a carapace consisting of dermal scutes with a highly mineralized surface plate and a compliant collagen base. This carapace must provide effective protection against predators as it comes at the high cost of reduced mobility and speed.

The Impact Behaviour of Crab Carapaces in Relation to Morphology [PDF]

open access: yesMaterials, 2020
Brachyuran crab carapaces are protective, impact-resistant exoskeletons with elaborate material microstructures. Though several research efforts have been made to characterise the physical, material and mechanical properties of the crab carapace, there are no studies detailing how crab morphologies might influence impact resistance. The purpose of this

Impact Resistant Structure Design and Optimization Inspired by Turtle Carapace

open access: yesMaterials, 2022
The turtle carapace has a high level of protection, due to its unique biological structure, and there is great potential to use the turtle carapace structure to improve the impact resistance of composite materials using bionic theory.

Carapace asymmetries in crabs

Crustaceana, 2018
AbstractThrough the geometric morphometric approach of the landmark-based method applied on adult right-handed specimens ofCarcinus aestuarii,Liocarcinus depuratorandPotamon fluviatile, statistical analyses showed significant outcomes for fluctuating asymmetry in the three studied species, and directional asymmetry only inP.

The structure of the ostracode carapace

Lethaia, 1972
The carapace ultrastructure of three Recent [Heterocypris incongruens (Ramdohr), Cypridopsis uidua (Muller), and Conchoecia belgica Muller] and one Cretaceous ostracode species [Cypridea propunctata Sylvester-Bradley] has been studied by means of standard electron microscope techniques. The carapace is shown to be an organic structure divisible into an

Protection mechanisms of the carapace of a box turtle

Journal of the Mechanical Behavior of Biomedical Materials, 2017
In this study we explore the materials design principles of the carapace of a Terrapene Carolina box turtle, which possesses a sandwich-like structure consisting of a foam-like interior layer (FIL) enclosed by two dense exterior layers (DEL). A constitutive scheme accounting for the large deformation, plastic yielding and post-yield strain hardening ...

Crab carapace hydrodynamics

Journal of Zoology, 1985
The hydrodynamic properties of the carapace of the swimming crab, ( Callinectes sapidus , Portunidae) and two dissimilar benthic species, Cancer productus and Lopholithodes mandtii , are investigated employing ...
