Electro-magnetic forces provide a potentially power full means in designing dynamic experiments with active control of the loading conditions. This article deals with the development of computational models to simulate the thermo-mechanical response of electro-magnetically loaded metallic structures. The model assumes linear electromagnetic constitutive equations and time-independent electric i...

Objective To establish a three-dimensional (3D) finite element (FE) model of ankylosing spondylitis (AS) kyphosis that is a digital platform for further studies. Methods A 30-year-old man with AS kyphosis underwent computed tomography transverse scanning from T1 to the sacrococcyx. The images were imported into Mimics® 17.0 software to establish a 3D model of the posterior spine, which was then...

An important technical issue in the enhanced geothermal system (EGS) is process of fracture shear and dilation, network propagation induced seismicity. EGS development requires an ability to reliably predict network’s permeability evolution. Laboratory field studies such as Collab Utah FORGE, modeling simulations provide valuable lessons for successful commercial design. In this work we present...

An innovative double-side welded rib-to-deck (RTD) joint has been developed recently to enhance fatigue performance of orthotropic steel decks (OSDs) in bridges. The welding residual stresses (WRS) will lead reduction resistance RTD joints It is essential study WRS and its distribution estimate the accurately. To investigate caused by process, experimental tests on four specimens were carried o...

A major computational issue in the finite element (FE) integration of coupled consolidation equations is the repeated solution in time of the resulting discretized indefinite system. Because of ill-conditioning, the iterative solution, which is recommended in large size 3D settings, requires the computation of a suitable preconditioner to guarantee convergence. In this paper the coupled system ...
