Magnesium and magnesium based alloys biomaterials are considered the most viable pragmatic choice of selection as biomedical alternatives for tissue repair damaged bones, vascular other biological disorders. Considering sensitivity health implication implanting foreign matter into human system, extensive studies required before clearance clinical trials is given. This often requires rigorous experimental evaluations biomechanical biodegradation properties such biomaterials, which expensive, time consuming practically demanding, several validation protocols. The technical advances in computing power well computational modeling techniques, finite element analysis, have been sort to address these limitations, but very little has catalogued reviews on basis their utilization sundry issues. paper attempts fill this gap by assessing from literature, how effective application analysis evaluation behaviour Mg-based systems use stents, screws, staples, implants orthopedic cardiovascular applications. review focuses factors geometric profile Mg material applicable physical constitutive laws, design parameters, boundary conditions stipulated, simulation outcomes, agreements with data, influence potentials real life designs biomaterial systems. Also, challenges that could affect effectiveness directions future improvements, were covered. will be immense benefit researchers, designers clinicians.

The design of efficient material-handling systems for milled lignocellulosic biomass is challenging due to their complex particle morphologies and frictional interactions. Computational modeling, including the discrete element method (DEM) continuum-based finite-element/volume methods, may offer scientific insight predictive capabilities flow in hoppers feeders. This article (Part II) presents a review current state-of-the-art continuum models biomass, whereas DEM are reviewed companion I). Advances numerical methods solve global governing equations discussed first, followed by comprehensive constitutive granular materials, Drucker–Prager, hypoplastic, Cambridge-type, inertial-rheology, nonlocal fluidity models. Specifically, we provide in-depth discussion on suitability those materials terms nonlinear elasticity, dependence strength pressure, density shear rate, compaction (dilation) associated with hardening (softening). Our study shows that, despite recent advances most suitable still need further development account material parametrization, multiflow regimes, multiscale behavior before they can be reliably used optimize operation handling systems.
