Finite element analysis of material and parameter effects in ballistic armors Balistik zırhlarda malzeme ve parametre etkilerinin sonlu elemanlar yöntemiyle analizi

Latif Tibet Aktaş

ABSTRACTBulletproof composite armor models are investigated using finite element software ANSYS/AUTODYN. A composite plate is modelled with Kevlar 29/epoxy, analysed, and the results obtained by this model are confirmed with the results available in the literature. Different materials are tested as secondary materials in the composite plate. The results obtained by these materials for unit weight and for residual velocities of the projectile are compared. A new stacking sequence study is conducted with the Kevlar 29/epoxy as primary material and Ultra High Molecular Weight Polyethylene (UHMWPE ...Daha fazlası

Design and development of the composite hydrogen storage tanks by using stochastic optimization methods Yüksek basınçlı kompozit hidrojen depolama tanklarının stokastik optimizasyon yöntemleri kullanılarak tasarlanması ve geliştirilmesi

Ozan Ayakdaş

ABSTRACTIn this thesis, there are five main objectives: (i) To calculate stress and strain components based on CLPT for only composite (Type IV and Type V) and aluminum-composite (Type III) pressure vessels (ii) To determine the burst pressure based on Classical Laminated Plate Theory and first ply failure theories for the cylindrical part of the Type III and Type V composite pressure vessels (iii) to compare the analytically calculated burst pressure values with the experimental and Finite Element Methods results in the literature (iv) to propose optimum stacking sequences designs for Type II ...Daha fazlası

Design and implementation of chaotic delta robot mixer system for preparing graphene nanocomposite coating Grafen nanokompozit kaplama hazırlanması için kaotik sistem tabanlı gürbüz delta robot sıvı karıştırıcı tasarımı ve gerçeklemesi

Kavur, Ali Emre

ABSTRACTThis thesis includes design, implementation and polymer nanocomposite mixing application of chaotic system based robust delta robot. Blending fluids is a vital process while preparing coating materials. The most commonly used the coating materials are polymeric materials which need to be blended in non-Newtonian fluids. This process is very critical and harder to achieve a perfectly prepared coating material.To achieve superior blending performance, two different and independent chaotic systems were used to chaotify delta robot-based blender system. One of them was used for chaotificat ...Daha fazlası

Development of microstructural and mechanical properties of aluminum alloys by equal channel angular pressing (ECAP) process Eş kanal açılı presleme (EKAP) yöntemiyle aluminyum alaşımlarının mikroyapı ve mekanik özelliklerinin geliştirilmesi

Yeşil, Mehmet Mahsun

ABSTRACTSevere Plastic Deformation (SPD), applying extreme force to alterate and refine the structures of materials permanently, have a huge potential to improve the mechanical and structural properties of materials superiously. ECAP is a kind of SPD techniques to produce submicron or nano sized grains in the material structure by applying stress to the sample passing through two angular intersected channels have the same diameters. ECAP has recently been becoming one of the most favourable candidate method in the production of nanostructured materials.One of the main objectives of this study ...Daha fazlası

Smart business accounting software as an android mobile application using artificial imtelligence

Okyay, Muhammet Serhat

In this study, the necessary data obtained from the databases (such as MSSQL, Mysql, Postgre SQL, etc.) of the softwares like ETA and NETSİS that are used for preaccountancy of the local and global companies were read, some of the data were written to the databases, and this data was used by the end user by using mobile phones or tablets carrying Android operating systems and working with Internet and cloud technology. In addition, new data sets that are collected on a cloud system from the accounting data while the company is on was studied by genetic algorithms which are one of the artificia ...Daha fazlası

Custom designed optical tweezer for trapping yeast cells

Çobanoğlu, Nur

The goal of this study is developing custom designed optical tweezer which uses two He-Ne lasers (λ=632.8 nm) parallel to each other to trap yeast cells. The characteristic specs of this optical tweezer determined by Brownian Motion of polystyrene beads in water. Stiffness and trapping forces of optical tweezer calculated for laser 1, laser 2 and when both lasers used simultaneously. Laser 2 can trap and move particle to laser 1 and multiple particles can be trapped by the laser 1. After determination of specs of optical tweezer, yeast cells in yogurt culture medium were trapped by lase ...Daha fazlası
