Hydrogen embrittlement of low carbon structural steel
(Elsevier Science Bv, Amsterdam, 2014)
Hydrogen embrittlement (HE) of steels is extremely interesting topic in many industrial applications, while a predictive physical model still does not exist. A number of studies carried out in the world are unambiguous ...
Numerical simulation of fatigue crack growth in friction stir welded T joint made of Al 2024 T351 alloy
(Elsevier Science Bv, Amsterdam, 2016)
The Extended Finite Element Method (xFEM) has been applied to simulate fatigue crack growth in an AA2024-T351 T welded joint, 5 mm thick, made by friction stir welding. The ABAQUS and Morfeo software has been used. Tensile ...
Design and testing characteristics of thin stainless steel diaphragms
(Elsevier Science Bv, Amsterdam, 2018)
Metal membranes are defined as thin steel circular plates. The metal membranes are widely used in the measurement technique and they are constantly loaded over the entire surface. In case that a membrane is loaded with ...
Heat transfer and lubrication of turboshaft motor-reducer
(Institute of Physics Publishing, 2018)
Turboshaft engines, as the rule, contains gear transmission unit - reducer and belong to the group of drive systems with the name motor-reducer. These are the compact and autonomous assemblies for various applications. In ...
Dynamic stability of high speed turboshaft engine with reducer
(Institute of Physics Publishing, 2018)
The dynamic behavior of machines which rotate at extreme high speeds is crucial for stable and long operation. In design process some dynamics calculation must be taken into account to avoid potential operation near resonance ...
True Stress-strain Curves for HSLA Steel Weldment - Iteration Procedure Based on DIC and FEM
(Elsevier, Amsterdam, 2020)
True stress-strain curves of HSLA steel welded joint regions were estimated by using numerical simulation of strains measured by DIC and special iteration procedure to match the results. Strains were measured at certain ...
Development of numerical-experimental model of connecting lugs and application on the lugs calculation of container terminals
(Elsevier Science Bv, Amsterdam, 2018)
The present paper describes numerical and experimental methodology and development of the model for stress and deformation state analysis of the connecting lug of container terminals. Numerical analysis was conducted by ...
Oxidation behavior during prolonged service of boiler tubes made of 2.25Cr1Mo and 12Cr1Mo0.3V heat resistance steels
(Elsevier Science Bv, Amsterdam, 2016)
During service of thermal power plant (TPP) units, different components are exposed to high temperature due to technological cycle of TPP unit. Service lifetimes of these components, especially boiler heating surfaces, may ...
Model analysis of complex structures - advantages of physical sub-scaled model testing and shortcomings in physical model production
(Elsevier Science Bv, Amsterdam, 2018)
The possibilities of testing real constructions strength are often limited, especially in case of large constructions. Testing on the model, instead of the actual construction, results in a great saving of money and time. ...
Towards a unified and practical industrial model for prediction of hydrogen embrittlement and damage in steels
(Elsevier Science Bv, Amsterdam, 2016)
Bearing in mind the multiple effects of hydrogen in steels, the specific mechanism of hydrogen embrittlement (HE) is active, depending on the experimental conditions and numerous factors which can be grouped as environmental, ...
