Analytical investigation and numerical simulation of the stress–strain state in mechanically heterogeneous welded joints with a single-V butt weld

Numerical investigation of the mechanical properties of a novel hybrid polymer composite reinforced with graphene and MXene nanosheets

“…Theoretical and numerical methods for investigation of nanoreinforced composites have been developed based on the combination of atomistic simulations and continuum and structural mechanics [18]. Among them, the finite element-based method is commonly used in evaluating the material properties and behavior [19][20][21][22] due to the maturity of contemporary microstructure development techniques and the advances in material modeling [23]. Nevertheless, the vast majority of research works utilizing the finite element-based approach were focused on graphene for improving the mechanical properties of nanocomposites [24][25][26].…”

Probability Assessment of the Mechanical and Low-Cycle Properties of Structural Steels and Aluminium

“…A considerable contribution to the calculation of probabilistic methods for mechanical and low-cycle properties was made by a series of investigators. Daunys et al [1][2][3][4] investigated the dependences of the low-cycle durability of mechanical properties for steels of welded joints used in nuclear power plants. Ellingwood et al [5,6] investigated the applicability of existing statistical data for describing the resistance of steel and reinforced concrete used in nuclear power plants.…”

“…Based on the topics discussed above, the main contributions of this paper are as follows: (1) We determine the distribution patterns of the mechanical properties, statistical parameters, and low-cycle fatigue curves; (2) we perform an analysis of the statistical assessment of cyclic elastoplastic strain diagrams and of the parameters; (3) we refine the low-cycle strength and durability calculations based on the verified values rather than standard values of key mechanical properties; and (4) we present a comparison of the low-cycle fatigue probability curves of the experimental data.…”

Numerical and Experimental Analysis of Welds in Steel Structural Element

“…Research of stresses in welds can also be performed e.g., using a digital camera, as in assessment of stress intensity factors for load-carrying fillet welded cruciform joints [25]. The publication [26] aims to investigate the stress-strain state in mechanically heterogeneous welded joints with a single-V butt weld by an analytical model along with a numerical simulation in ABAQUS finite element analysis software. From the above summary of publications aimed at mathematical modeling of structures, focusing on the problems of welded oriented problems is obvious that this is a very current topic.…”
