Current hip replacement femoral implants are made of fully solid materials which all have stiffness considerably higher than that bone. This mechanical mismatch can cause significant bone resorption secondary to stress shielding, lead serious complications such as peri-prosthetic fracture during or after revision surgery. In this work, a high strength porous material with tunable properties is introduced for use in design. The implant macro geometry based off short stem taper-wedge...
A snapping mechanical metamaterial is designed, which exhibits a sequential snap-through behavior under tension. The tensile response of this can be altered by tuning the architecture segments to achieve range nonlinear responses, including monotonic, S-shaped, plateau, and non-monotonic behavior.
Revision surgeries of total hip arthroplasty are often caused by a deficient structural compatibility the implant. Two main culprits, among others, bone-implant interface instability and bone resorption. To address these issues, in this paper we propose novel type implant, which, contrast to current replacement implants made either fully solid or foam material, consists lattice microstructure with nonhomogeneous distribution material properties. A methodology based on multiscale mechanics...
Even in a well-functioning total hip replacement, significant peri-implant bone resorption can occur secondary to stress shielding. Stress shielding is caused by an undesired mismatch of elastic modulus between the stiffer implant and adjacent tissue. To address this problem, we present here microarchitected that consists three-dimensional (3D) graded lattice material with properties are mechanically biocompatible those femoral bone. Asymptotic homogenization (AH) used numerically determine...
The coefficient of thermal expansion (CTE) architected materials, as opposed to that conventional solids, can be tuned zero by intentionally altering the geometry their structural layout. Existing material architectures, however, achieve CTE tunability only with a sacrifice in efficiency, i.e. drop both stiffness mass ratio and strength ratio. In this work, we elucidate how resolve trade-off between efficiency present lightweight bi-material architecture not is stiffer stronger than other 3D...
Abstract Self‐healing electronic materials are of primary interest for bioelectronics and sustainable electronics. In this work, autonomic self‐healing films obtained from mixtures the conducting polymer poly(3,4‐ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS) polyethylene glycol (PEG) is reported. The presence PEG in PEDOT:PSS decreases elastic modulus increases elongation at break, thus leading to a softer material enhanced characteristics. situ imaging cutting/healing...
Abstract Origami crease patterns have inspired the design of reconfigurable materials that can transform their shape and properties through folding. Unfortunately, most designs cannot provide load-bearing capacity, those can, do so in certain directions but collapse along direction deployment, limiting use as structural materials. Here, we merge notions kirigami origami to introduce a rigidly foldable class cellular metamaterials flat-fold lock into several states are stiff across multiple...
