Fishnet model for failure probability tail of nacre-like imbricated lamellar materials.
Nacre, the iridescent material of the shells of pearl oysters and abalone, consists mostly of aragonite (a form of CaCO3), a brittle constituent of relatively low strength ([Formula: see text]10 MPa). Yet it has astonishing mean tensile strength ([Formula: see text]150 MPa) and fracture energy ([Formula: see text]350 to 1,240 J/m2). The reasons have recently become well understood: (i) the nano...
متن کاملFailure mode transition in nacre and bone-like materials.
Mineralized biological materials such as nacre or bone achieve remarkable combinations of stiffness and toughness by way of staggered arrangements of stiff components (nanoscale or microscale fibers or tablets) bonded by softer materials. Under applied stress these components slide on one another, generating inelastic deformations and toughness on the macroscale. This mechanism is prominent in ...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولDesigning nacre-like materials for simultaneous stiffness, strength and toughness_ Optimum materials, composition, microstructure and size
Nacre, bone and spider silk are staggered composites where inclusions of high aspect ratio reinforce a softer matrix. Such staggered composites have emerged through natural selection as the best configuration to produce stiffness, strength and toughness simultaneously. As a result, these remarkable materials are increasingly serving as model for synthetic composites with unusual and attractive ...
متن کاملRisk Factors for Failure of Keratoplasty in Keratoconus: Penetrating vs. Deep Anterior Lamellar Keratoplasty
Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
