TL;DR: In this article, the von Mises yield criterion and the Reuss stress-strain relations were used for the determination of the stresses and warping in a partly plastic thin tube of arbitrary section.
Abstract: Summary Equations for the determination of the stresses and warping in a partly plastic thin tube of arbitrary section are obtained for any monotonic loading by bending and twisting couples. The analysis is based on the von Mises yield criterion and the Reuss stress-strain relations. The equations are solved numerically for a circular tube for various loading programmes.

TL;DR: In this paper, a numerical model to perform non-linear analysis of building floor structures is proposed, which is derived from the Kirchhoff's plate bending formulation of the boundary element method (BEM) for zoned domains, in which the plate stiffness is modified by the presence of membrane effects.
Abstract: In this work, a numerical model to perform non-linear analysis of building floor structures is proposed. The presented model is derived from the Kirchhoff's plate bending formulation of the boundary element method (BEM) for zoned domains, in which the plate stiffness is modified by the presence of membrane effects. In this model, no approximation of the generalized forces along the interface is required and the compatibility and equilibrium conditions along interfaces are imposed at the integral equation level. In order to reduce the number of degrees of freedom, the Navier–Bernoulli hypothesis is assumed to simplify the strain field for the thin sub-regions (rectangular beams). The non-linear formulation is obtained from the linear formulation by incorporating initial internal force fields, which are approximated by using the well-known cell sub-division. Then, the non-linear solution of algebraic equations is obtained by using the concept of the consistent tangent operator. The Von Mises criterion is adopted to govern the elasto-plastic material behaviour checked at points along the plate thickness and along the rectangular beam element axes. The numerical representations are accurately obtained by either computing analytically the element integrals or performing the numerical integration accurately using an appropriate sub-elementation scheme.

TL;DR: In this article, the authors developed a theoretical model of the mechanical behavior of the twill weave based on previous researches concerning the simplest plain weave, and the coefficients from those formulas are then used in the Modulef software.
Abstract: The arrangement as well as the properties and the structure of the fibres within the yarn and the yarns within the fabric generate a complex mechanism of deformation in such material. Therefore, intends to develop a theoretical model of the mechanical behaviour of the twill weave based on previous researches concerning the simplest plain weave. However, scaling up from the plain to the twill weave is not a direct transformation due to the non‐symmetry of the latter. The finite element method does not require simplifying hypotheses. Thus, it is possible to simulate different stresses, to determine the fabric response and to compare the behaviour of the various structures. This simulation requires the use of a realistic meshing of the basic cell and an accurate characterisation of the physical parameters of the material that composes the basic cell. Assuming the material to be elastic, the derived and, consequently, the discreet mathematical formulations of the problem have both been solved. The coefficients from those formulas are then used in the Modulef software. For each stage of the development, uniaxial, biaxial and perpendicular to the fabric plan, tensile tests have been simulated, as well as pure shear testing. The next step consisted of computing the Tresca and Von Mises stresses within the basic cell and the micro‐stress field within the basic cell components.

TL;DR: In this article, a new experimental technique is proposed for measuring the strain to fracture for sheet metal after proportional loading under plane strain conditions, which makes use of a mini-Nakazima specimen that is clamped onto a 30-mm diameter die and subjected to out-of-plane loading through a dihedral punch.

TL;DR: There were different patterns of stress-strain distribution at bone-implant interface between the studied attachment designs, and Hader bar-clip attachment showed better biomechanical behavior than adding ERA studs distal to hader bar.
Abstract: PURPOSE. This study was accomplished to assess the biomechanical state of different retaining methods of bar implant-overdenture. MATERIALS AND METHODS. Two 3D finite element models were designed. The first model included implant overdenture retained by Hader-clip attachment, while the second model included two extracoronal resilient attachment (ERA) studs added distally to Hader splint bar. A non-linear frictional contact type was assumed between overdentures and mucosa to represent sliding and rotational movements among different attachment components. A 200 N was applied at the molar region unilaterally and perpendicular to the occlusal plane. Additionally, the mandible was restrained at their ramus ends. The maximum equivalent stress and strain (von Mises) were recorded and analyzed at the bone-implant interface level. RESULTS. The values of von Mises stress and strain of the first model at bone-implant interface were higher than their counterparts of the second model. Stress concentration and high value of strain were recognized surrounding implant of the unloaded side in both models. CONCLUSION. There were different patterns of stress-strain distribution at boneimplant interface between the studied attachment designs. Hader bar-clip attachment showed better biomechanical behavior than adding ERA studs distal to hader bar. [J Adv Prosthodont 2013;5:333-40]
