Fins incorporated into the design of a dynamic cervical spine implant have been employed to enhance axial load- bearing ability, yet their true biomechanical advantages, if any, have not been defined. Therefore, the goal of this study was to assess the biomechanical and axial load-bearing contributions of the fin components of the DOC ventral cervical stabilization system. Eighteen fresh cadave...

The present work addresses the problem of maximizing a structure load-bearing capacity subject to given material strength properties and volume constraint. This can be viewed as an extension limit analysis problems which consist in finding maximum load for fixed geometry. We show that it is also closely linked minimizing total under constraint carrying loading. Formulating these topology optimi...

Surfaces can be slippery or sticky depending on surface chemistry and roughness. We demonstrate in atomistic simulations that regular and random slip patterns on a surface lead to pressure excursions within a lubricated contact that increase quadratically with decreasing contact separation. This is captured well by a simple hydrodynamic model including wall slip. We predict with this model that...

Use of auxiliary elements in refining and betterment of engineering properties of soil have gained attention since a long time ago. Nowadays the effectiveness and capability of the soil reinforcing technique for giving proper practical solutions in various projects have resulted in this technique quickly gaining a place in geotechnical engineering. In this paper, the results of laboratory studi...

Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can affect the load-bearing capacity of the members and consequently that of the structure. The double-layer space trusses are susceptible to progressive collapse due to sudden buckli...

Abstract Wall systems have a wide range of embodied energy due to the diversity materials available. This paper analyzes expenditure and carbon dioxide emissions in internal external wall (IEWS) rural residence social interest Cascavel, state Paraná, Brazil. The methodology proposed by NBR ISO 14040 was used perform life-cycle assessment (LCEA) (LCCO2A) these systems. Four scenarios were consid...
