Journal ArticleDOI
Finite Element Analysis and Understanding the Biomechanics and Evolution of Living and Fossil Organisms
TL;DR: Finite element analysis has much potential in addressing questions of form-function relationships, providing appropriate questions are ask, and explicit hypothesis-testing bridges these two standpoints.
Journal ArticleDOI
Cranial design and function in a large theropod dinosaur
Emily J. Rayfield,David B. Norman,David B. Norman,Celeste C. Horner,John R. Horner,Paula Smith,Jeffrey J. Thomason,Paul Upchurch +7 more
TL;DR: This work has generated the most geometrically complete and complex FEA model of the skull of any extinct or extant organism and used this to test its mechanical properties and examine, in a quantitative way, long-held hypotheses concerning overall shape and function.
Journal ArticleDOI
What makes an accurate and reliable subject-specific finite element model? A case study of an elephant femur (Retraction of vol 9, pg 351, 2012)
Olga Panagiotopoulou,Simon Wilshin,Emily J. Rayfield,Sandra J. Shefelbine,John R. Hutchinson +4 more
TL;DR: It is emphasized how considering heterogeneous material properties in FEA may be critical, so this should become standard practice in comparative FEA studies along with convergence analyses, consideration of element size, type and experimental validation.
Journal ArticleDOI
A virtual world of paleontology
John A. Cunningham,Imran A. Rahman,Stephan Lautenschlager,Emily J. Rayfield,Philip C. J. Donoghue +4 more
TL;DR: This work states that new protocols allow more objective reconstructions of fossil organisms, including soft tissues, from incomplete remains, and can be used in functional analyses, rigorously testing long-standing hypotheses regarding the paleobiology of extinct organisms.
Journal ArticleDOI
Patterns of morphospace occupation and mechanical performance in extant crocodilian skulls: a combined geometric morphometric and finite element modeling approach.
TL;DR: It is shown that biomechanical stress and the hydrodynamic properties of the skull show a strong relationship with the distribution of crocodilians in skull morphospace, whereas phylogeny and biogeography show weak or no correlation.
