Wound Composite

A mechanical and optimal analyses procedure is developed to assess the stresses and deformations of Novel Wound Composite Axial-Impeller under loading conditions particular to centrifuge. This procedure is based on an analytical method and Finite Element Analysis (FEA, commercial software ANSYS) results. A low-cost, light-weight, high-performance, composite turbomachinery impeller from differently designed patterns will be evaluated. Such impellers can economically enable refrigeration plants using water as a refrigerant (R718). To create different complex patterns of impellers, MATLAB is used for creating the geometry of impellers, and CAD software UG is used to build three-dimensional impeller models. Available loading conditions are: radial body force due to high speed rotation about the cylindrical axis and fluid forces on each blade. Two-dimensional plane stress and three-dimensional stress finite element analysis are carried out using ANSYS to validate these analytical mechanical equations. The von Mises stress is investigated, and maximum stress and Tsai-Wu failure criteria are applied for composite material failure, and they generally show good agreement.

Present research endeavours towards the development of a methodology to enhance the life of hyperelastic materials in automotive suspension (leaf spring) system. The durability of the elastomeric (rubber) material in the insert was determined at various loading conditions for better operation. Three different rubber materials were used as the models including the currently used rubber material in the suspension system. The non-linear finite element analysis was carried out for the three different materials with the uniaxial stress–strain data as the input source for the material properties. A suitable hyperelastic model was also used as the input for determining the deformation and the stress concentration in the leaf spring tip insert. The failure of the tip insert was determined in various loading conditions and the best design for limited stress concentration with higher reliability was determined in the three models. The overall results are tabulated and compared for better utilization of rubber as a tip insert in the automotive industry.

Implant Treatment

In most patients with complete or partially stretched edentations requiring a dental implant, there is insufficient alveolar bone for a proper morpho- functional prosthetic restoration. Therefore, in many cases a bone addition is required for the implant treatment. The aim of this study is to evaluate ex-vivo, with numerical simulations, a large mandibular bone defect that is restored by using a three-dimensional (3D) printed ceramic scaffold. In order to obtain a proper morphological and functional prosthetic restoration, a thick mandibular bone is utilized for the implant treatment. The polymeric scaffold is attached to the mandibular bone with one, two, or three implants. By scanning the mandible with MicroScribe 3G and then employing a Finite Element Analysis (FEA) with Pro/Engineer and ANSYS 15, the study performs a numerical simulation and thus assesses the effects of the force applied to the scaffold.
