PERFORMANCE OF WELDED JOINT UNDER THICKNESS-DIRECTIONAL STRESS CONDITION

Speech Recognition under Stress Condition

The objective of this work is to conduct a speech recognition study and evaluate the performance of the same under stressed condition. The speech recognition study is conducted both in isolated word recognition and keyword spotting approaches. The word models are built during training using speech collected from neutral condition. During testing these models are tested with speech signals colle...

Effect of Stress Triaxiality on Yielding of Anisotropic Materials under Plane Stress Condition

The triaxiality of the stress state is known to greatly influence the amount of plastic strain which a material may undergo before ductile failure occurs. It is defined as the ratio of hydrostatic pressure, or mean stress, to the von Mises equivalent stress. This paper discusses the effects of stress triaxiality on yielding behavior of anisotropic materials. Hill-von Mises’s criteria for anisot...

Tensile Properties of Ferrite-austenitic Welded Joint

Very often, in order to optimized welded constructions, some of their parts are made of heterogeneous steels. For example, microalloyed steels are in use for cars chassis making and high alloyed steels for different constructions making. From that reason, it’s not rare to find welded joints between ferrite microalloyed and austenitic highalloyed steels. As a rule, these joints are welded by usi...

Free Expansion and Thermal Stress Analysis of a Corner Welded Joint by Finite Element Method

In Arc welding heat is transferred to the joint by an electrode. During manual metal Arc Welding this heat is transferred by melting the electrode. The stresses generated in welded plate are due to temperature raise and can be simple and thermal stresses. The stresses generated will cause distortion and changing the shape of the welded plates. The study of the distortion and residual stresses i...
