Abstract The main objective of this study is to fabricate a Novel bio-inspired lattice structure for energy absorption. A design was proposed based on the microstructure one various butterfly species Papilio Xuthus. Two major parameters are chosen from make multiple designs which may cause changes in behavior among all available parameters. parametric values required were calculated with help R...

In this section, we provide specific information on our experimental apparatus. For all of our experiments we used a universal testing machine (Instron 5943, Norwood, MA) with a 10 N low-profile static load cell (2530 from the same manufacturer). The displacement and force resolutions were 10−4 mm and 10−4 N, respectively. Our experiments involved measuring displacements and forces of ∼ 10 mm a...

  Objective: Repair of an indirect restoration is usually preferred over its replacement. This study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin.   Methods: For this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following ...

  Objective: The diagnosis of vertical root fracture (VRF) in endodontically treated teeth is a clinical challenge due to lack of specific clinical and radiographic signs. Although radiographic evaluation such as CBCT is helpful, intracanal posts can produce artifacts and may impair the quality of CBCT scans. This study aimed to compare the diagnostic accuracy of different resolutions of CBCT i...

Abstract Torsion tests provide important shear stress and strain relationships to reveal the fundamental plastic flow response of a material. Bespoke torsion techniques complemented by digital image correlation are developed accurately measure stress–strain relationship at quasi-static, medium rate 9/s, high above 1000/s. The equipment used includes screw-driven mechanical system, hydraulic Ins...
