In this thesis, the experiments with HSLA600 which is widely used in industry will be investigated. Single, double and triple pulse welding will be applied to the materials to obtain the biggest, homogenous nugget geometry ...

This thesis aims to examine the joining of steel sheets with a yield strength of up to 1500MPa and aluminum materials by using resistance spot welding (RSW). Effect of electrode geometry and its combinations on the quality ...

The aim of this thesis is to design a novel constant-force compliant gripper mechanism. The design is a monolithic holding mechanism which is fixed on one side and free on the gripper side. The mechanism has four compliant ...

Ceramic armors have been developed to provide high ballistic protection with low density. Ceramic armors consist of three basic components, these are: the ceramic tile, the ductile backing plate, and the adhesive to bond ...

Hybrid composite materials are a specialized version of composite materials that constitute at least two different fiber materials. Hybrid composites are promising materials for various engineering applications. These ...

Under a specific loading condition, the canister front cover must fracture in a predetermined direction upon impact from the missile radome. To prevent the broken pieces from come into contact with on the missile body, ...

Shape Memory Alloys (SMAs) are very special materials with their distinctive ability to recover their shape change by phase transformation via mechanical and/or thermal stimulations. When the alloy heated above a certain ...

Knowing the mechanical behavior of fiber-reinforced composites are important since unidirectional (UD) composite materials have been widely used in many industries. Different methods in macro-scale and micro-scale have ...

A naturally fragmenting 81mm mortar round's effectiveness was investigated. During this investigation sustainable new methods were tried. The fragmentation of the round by explosives were examined by tests, modelled ...

In the scope of the thesis an alternative longitudinal flight control algorithm, which satisfies predefined stability and performance requirements, in case of a specific fault is aimed for a jet trainer aircraft. Base ...
