Journal ArticleDOI
Energy absorbent natural materials and bioinspired design strategies: A review
Joanna McKittrick,Po-Yu Chen,Luca Tombolato,Ekaterina Novitskaya,M.W. Trim,Gustavo A. Hirata,Eugene A. Olevsky,Mark F. Horstemeyer,Marc A. Meyers +8 more
TL;DR: In this paper, the authors examined several mammalian structural materials: bones (bovine femur and elk antler), teeth and tusks from various taxa, horns from the desert big horn sheep, and equine hooves.
Journal ArticleDOI
The effects of water and microstructure on the mechanical properties of bighorn sheep (Ovis canadensis) horn keratin.
M.W. Trim,Mark F. Horstemeyer,Hongjoo Rhee,Haitham El Kadiri,Lakiesha N. Williams,Jun Liao,Keisha B. Walters,Joanna McKittrick,Seong Jin Park +8 more
TL;DR: In this paper, the authors quantified various parametric effects important to the microstructure and mechanical property relationships of the bighorn sheep horn and found that water has a more significant effect on the mechanical behavior of ram horn more than the anisotropy, location along the horn and the type of loading state.
Journal ArticleDOI
Moisture, anisotropy, stress state, and strain rate effects on bighorn sheep horn keratin mechanical properties
Kyle Johnson,M.W. Trim,D.K. Francis,Wilburn R. Whittington,Jonathan Miller,C.E. Bennett,Mark F. Horstemeyer +6 more
TL;DR: The structure-property relationships quantified here for bighorn sheep Horn keratin can be used to help validate finite element simulations of ram's impacting each other as well as being useful for other analysis regarding horn keratin on other animals.
Journal ArticleDOI
Geometric Effects on Stress Wave Propagation
Kyle Johnson,M.W. Trim,Mark F. Horstemeyer,Nayeon Lee,Lakiesha N. Williams,Jun Liao,Hongjoo Rhee,Raj Prabhu +7 more
TL;DR: The combined taper and spiral optimized stress wave mitigation in terms of the pressure and impulse is evaluated, providing insight into the ram's horn design and woodpecker hyoid designs found in nature.
Journal ArticleDOI
Finite element analysis of a ram brain during impact under wet and dry horn conditions.
Karlee Johnson,M.W. Trim,Y. Mao,Hongjoo Rhee,Lakiesha N. Williams,Jun Liao,J.A. Griggs,Mark F. Horstemeyer,Yuanyuan Duan +8 more
TL;DR: In this paper, Ram impacts at 5.5m/s were simulated through finite element analysis in order to study the mechanical response of the brain, and an acceleration as high as 607 g's was observed, which is an order of magnitude higher than predicted brain injury threshold values.
