Abstract Background Experimental analyses of the 3D strain field evolution during loading allows for better understanding deformation and failure mechanisms at meso- microscale in different materials. In order to understand auxetic behaviour delamination process paperboard materials tensile deformation, it is essential study out-of-plane component tensor that is, contrast previous 2D studies, o...

Abstract In the last few years, Fused Filament Fabrication is growing in industrial field for manufacture of final products by using new materials with high mechanical performances. Among those, one strongest Carbon-PA. This a composite material made Nylon thermoplastic matrix filled short carbon fibers reinforces. The aim this work to investigate its properties static and dynamic conditions. C...

In this work, we propose a comprehensive multi-scale three-dimensional (3D) resistor network numerical model to predict the piezoresistivity behavior of a nanocomposite material composed of an insulating polymer matrix and conductive carbon nanotubes (CNTs). This material is expected to be used as highly sensitive resistance-type strain sensors due to its high piezoresistivity defined as the re...

AIMS Two-dimensional speckle-tracking echocardiography (2D-STE) is limited by its inability to track tissue motion in three dimensions. This is particularly relevant in heart transplant recipients, in whom marked translational motion of the transplanted heart is present. We aimed to compare 3-dimensional (3D)- and 2D-STE-derived strain parameters, and to identify clinical features associated wi...

background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...
