This paper deals with the modeling of punching shear failure in reinforced concrete slabs using nonlinear finite element analysis. The 3D finite element analyses (FEA) were performed with the appropriate modeling of element size and mesh, and the constitutive modeling of concrete. The FE numerical models are validated by comparing with the experimental results obtained from tested specimens and...

latticed columns are frequently used in industrial steel structures. in some countries these built-up columns might be even used in other types of steel structures such as residential and commercial buildings. besides, latticed columns are parts of skeletons of many historic buildings all around the world. to analyze a steel structure with latticed columns a more accurate numerical model for su...

Passivation hermiticity is always a concern in integration circuit fabrication and application. Passivation stress is one of the key factors for the passivation integrity. In this paper, passivation stress is investigated as a function of top metal profiles with a 3Dimentional Finite Element Modeling (3D FEM). A new structure is proposed for reducing the passivation stress at the corner of a to...

background: the salvage proximal femoral osteotomy is performed in mild or moderate osteoarthritis when the articulating surfaces are normal and relieves the subject’s pain. because the importance of angular mal-alignment of the femur bone at the hip junction accurate pre-op planning based on patient specific anatomy is required to prevent any lower limb misalignment and joint problem pre-opera...

The paper presents some researches concerning the mechanical properties of composite materials used for prosthetic dental elements. After a short introduction concerning the general strains and loads that usually apply upon prosthetic works, the authors present the virtual model of a molar tooth subjected to the most common actions, using finite element method. Then the results are further show...

We introduce a method for 3D implicit geological structural modeling from sparse sample points, where several conformable surfaces are represented by one single scalar field. Laplacian and Hessian regularization energies discretized on tetrahedral mesh using finite elements. This scheme is believed to offer some geometrical flexibility as it readily implemented both structured unstructured grid...

In order to simulate the mechanical behavior of large structures assembled from thin composite panels, we propose a coupling technique which substitutes local 3D models for the global plate model in the critical zones where plate modeling is inadequate. The transition from 3D to 2D is based on stress and displacement distributions associated with Saint-Venant problems which are precalculated au...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...
