The critical conditions leading to fracture in elongation and different types of flow instabilities were examined in uniaxial elongation and in a capillary rheometer equipped with dies having different entry profiles. Either ductile or brittle fracture may ...
In this paper, two brittle fracture problems are numerically simulated: the failure of a ceramic ring under centrifugal loading and crack branching in a PMMA strip. A three-dimensional finite element package in which cohesive elements are dynamically inser ...
The cement for surgical purposes includes three components. The first component includes beta tertiary calciumphosphate beta-Ca3(PO4)2(beta-TCP) particles; and monocalcium phosphate Ca(H2PO4)2(MCPA) or monocalcium phosphate monohydrate Ca(H2PO4).H2O (MCPM) ...
Fiber push-out tests have been performed on a ceramic matrix composite consisting of Carborundum sintered SiC fibers, with a BN coating, embedded in a reaction-bonded SiC matrix. Analysis of the push-out data, utilizing the most complete theory presently a ...
During knee flexion, the human patella moves along a complex path resulting from the combined actions of articular contact and soft-tissue stabilization. The current study is an attempt to characterize the role of these soft structures on patellar kinemati ...
The distribution of (elastic) lattice strains following plastic deformation of an aluminium alloy is examined using finite element simulations of aggregates with individually resolved crystals. The aggregates consist of face centred cubic crystals with ini ...
In considering the problem of inverse modeling of tiltmeter data for hydraulic fracture mapping, we address the issues of selecting the elastic model to represent the hydraulic fracture and limitations imposed by distance and fracture size on the informati ...
Correct positioning of the tibial component in total knee arthroplasty (TKA) must take into account both an optimal bone coverage (defined by a maximal cortical bearing with posteromedial and anterolateral support) and satisfactory patellofemoral tracking. ...
