Influence of internal defects on filament wound SiC/SiC composite tubes on their mechanical behavior under uniaxial tension

SiC/SiC composites are resistant to high temperatures making them excellent candidates for aeronautical or nuclear applications. The paper examines the robustness of the mechanical behavior of SiC/SiC tubes for fuel cladding in pressurized light…

Mechanical micromodeling of stress-shielding at the bone-implant interphase under shear loading

Inserting a titanium implant in bone tissue may modify its physiological loading and therefore cause bone resorption, via a phenomenon called stress-shielding. The local stress field around the bone-implant interphase (BII) created under shear…

An examination of local strain fields evolution in ductile cast iron through micromechanical simulations based on 3D imaging

Microscopic digital volume correlation (DVC) and finite element precoalescence strain evaluations are compared for two nodular cast iron specimens. Displacement fields from \textit{in-situ} 3D synchrotron laminography images are obtained by DVC…

Digital Volume Correlation for Large Deformations of Soft Tissues: Pipeline and Proof of Concept for the application to Breast ex vivo Deformations

Being able to reposition tumors from prone imaging to supine surgery stances is key for bypassing current invasive marking used for conservative breast surgery. This study aims to demonstrate the feasibility of using Digital Volume Correlation (DVC)…

On two simple virtual Kirchhoff-Love plate elements for isotropic and anisotropic materials

Abstract The virtual element method allows to revisit the construction of Kirchhoff-Love elements because the $$C^1$$ C 1 -continuity condition is much easier to handle in the VEM framework than in the traditional Finite Elements methodology. Here…
