The influence of strut waviness on the tensile response of lattice materials
P. E. Seiler, K. Li, V. S. Deshpande +1
Recent advances in additive manufacturing methods make it possible, for the first time, to manufacture complex micro-architectured solids that achieve desired stress versus strain…
Regulation of notch sensitivity of lattice materials by strut topology
K. Li, P. E. Seiler, V. S. Deshpande +1
We propose a local reinforcement technique for lattices in the vicinity of a stress-raiser such as a notch, in order to elevate the macroscopic strength and ductility. A spatially…
Nanofibril-mediated Fracture Resistance of Bone
Ottman A. Tertuliano, Bryce W. Edwards, Lucas R. Meza +2
Natural hard composites like human bone possess a combination of strength and toughness that exceeds that of their constituents and of many engineered composites. This augmentation…
An assessment of the J-integral test for a metallic foam
H. C. Tankasala, T. Li, P. E. Seiler +2
An assessment is made of the J-integral test procedure for initial crack growth in an open-cell aluminium alloy foam by combining finite element (FE) simulations with experiment. I…
A versatile numerical approach for calculating the fracture toughness and R-curves of cellular materials
Meng-Ting Hsieh, Vikram S. Deshpande, Lorenzo Valdevit
We develop a numerical methodology for the calculation of mode-I R-curves of brittle and elastoplastic lattice materials, and unveil the impact of lattice topology, relative densit…
