Abstract:

The present paper, describes a transient translating elasto-plastic thermo-mechanical finite element model to study 2-D frictional rolling contact. Frictional two-dimensional contact is simulated by repeatedly translating a non-uniform thermo-mechanical distribution across the surface of an elasto-plastic half space. The half space is represented by a two dimensional finite element mesh with appropriate boundaries. Calculations are for an elastic-perfectly plastic material and the selected thermo-physical properties are assumed to be temperature independent. The paper presents temperature vari

Abstract:

Hull structures such as stiffened plates and thin panels are the building blocks of ship structures, and therefore understanding their manufacturing process is of utmost importance. The welding process has been widely used to join stiffeners, stringers, and girders onto the plate. The thermo-mechanical loading and constraints during the welding process generally induced deformations and residual stresses. A deep understanding of the process parameters during thermo-mechanical processing is required to control the process-induced deformation. Therefore, this study aims to investigate the deform

Abstract:

The dynamic problem of thermo-elastic-viscous-plastic deformation of shallow composite shells is formulated using the refined theory of bending. In this case, tangential displacements along the thickness of constructions are approximated by polynomials of the third and higher orders, and the deflection does not depend on the transverse coordinate. Normal transverse stresses in the composition have a linear distribution over the thickness. The temperature over the thickness of the curved panels is approximated by a 7th order polynomial. The geometric nonlinearity of the problem is taken into ac

Abstract:

Predicting residual stresses arising from the thermal and mechanical loading history during engineering processes including welding would be a viable tool to reach the optimum process parameters. In the present article, an elasto-thermo-visco-plastic model has been employed to estimate the residual stress caused by the underwater friction stir welding, which are resulted by large thermo-mechanical deformations on one hand and rapid cooling arising from the enormous non-uniform boiling heat convention of water on the other hand. Finally, the numerical results are compared with experimental data

Abstract:

The purpose of this article is to better understand the behavior of the residual stresses in aluminium alloy plates by using mathematical modelling. Quenching of aluminium alloy plates causes an uneven temperature variation in aluminum alloy plates, and elastic and elasto-plastic deformations occur inside the material. The latter causing the formation of deformations and residual stresses. The non-linear thermo-mechanical direct coupled analysis of the quenching process for a 6061 aluminium alloy plate was achieved by using ANSYS ﬁnite element software.

Abstract:

Classical studies of the ratcheting of pressure vessels under thermocyclic loading assume that the structural material is elastic-plastic without hardening (ideal plasticity). This allows for an analytical solution to the problem, which is typically presented in the form of a "Brie diagram" plotted on the axes of mechanical and thermal stresses. The actual behavior of a material under cyclic thermo-mechanical loading requires more complex mathematical models that consider isotropic, kinematic, or mixed isotropic-kinematic hardening effects.

As a result, the railways are subjected to additional loads which produce a higher level of strains and stresses. The rolling contact of a wheel on a rail is the basis of many rail-wheel related problems including the rail corrugation, wear, plastic deformation, rotating interaction fatigue, thermo-elastic-plastic behavior in contact, fracture, creep, and vehicle dynamics vibration. Therefore,

Abstract:

Laser Shock Peening (LSP) turned out to be the most efficient surface engineering process for advanced materials to induce beneficial deep compressive residual stress which helps in improving mechanical, fatigue properties and surface damage resistance. But, analyzing the nonuniform distribution of residual stresses in the treated sample with X-ray diffraction (XRD) is much time taking and a costly process. This problem can be resolved with LSP finite element numerical simulation model which is feasible with the realistic experimental process. The FE model allows the user to control the laser

Abstract:

BACKGROUND: At considering the issues of crawler tractors interaction with soil the determining factor is the time-varying impact of loads on the soil layer, its stressed and strained state, which, in turn, directly depends on its stress-strain properties. The properties assessment should be carried out with a rheological approach, which allows to explain many phenomena and processes and to develop new high technologies in terms of the criterion of minimizing the impact on the soil. AIMS: Studying the compacting ability of a crawler tractor in a configuration in various machine-tractor u

Abstract:

In this work, the problem of deforming an elastoplastic cylinder during a hot landing on a viscoelastic shaft has been solved numerically. The problem is written for a non-stationary temperature change, using the assumption of a generalized flat deformable state in the shaft-cylinder system. Accounting for the accumulation of irreversible plastic deformations in the cylinder is carried out by the method of additional deformations. The flow surface is given by the Huber–Mises equation. Viscoelastoplastic shaft deformation is described by the Boltzman–Volterra equations.

Abstract:

Energy tunnels are typically comprised of tunnel linings that are equipped with heat transfer pipes, thereby converting them into tunnel ground heat exchangers (tunnel GHEs). This innovative technology offers renewable methods of space heating, cooling and hot water production. While still relatively uncommon, it is becoming increasingly popular due to the growing interest in sustainability and innovation, particularly in large infrastructure projects [8, 7, 10]. Additionally, the increasing need for clean and renewable sources of energy has made energy tunnels an attractive solution for addre

Abstract:

Application of engineered wood, especially in the form of glued-laminated timbers has increased significantly. Recent progress in plywood made of high strength and high stiffness hardwoods, like European beech, gives designers in general more freedom by increased dimensional stability and load-bearing capacity. However, the strong hygric dependence of basically all mechanical properties renders many innovative ideas futile. The tendency of hardwood for higher moisture sorption and swelling coefficients lead to significant residual stresses in glued-laminated configurations, cross-laminated pat

AbstractIn the field of material modeling, thermoplastic polymers are often studied because of their complex material behavior and their prevalence in industry applications due to their low cost and wide range of applications. Nowadays, where reusability becomes more and more important, materials which can undergo reversible thermomechanical deformations are appealing for, e.g., the construction of car body components. To predict such complex forming processes with multiple influencing factors, such as temperature, strain rate or underlying material morphology, model formulations are needed th

AbstractWe demonstrate that the high temperature polymorphic tantalum phase transition from the tetragonal beta phase to the cubic alpha phase causes complete stress relaxation and a large decrease in the resistance of tantalum thin films. 100 nm beta tantalum thin films were deposited onto thermally oxidized <100> silicon wafers by dc magnetron sputtering with argon. In situ stress and resistance at temperature were measured during temperature-ramped annealing in purified He. Upon heating, films that were initially compressively stressed showed increasing compressive stress due to therm

Several applications which are framed in the energy geotechnics field, particularly the design of energy geo-structures, energy geo-storage, enhanced geothermal energy systems and radioactive waste disposal, require a thorough thermo-hydro-mechanical (THM) characterisation of their host soil/rock formation. The present study comes up from the need to investigate the THM behaviour of deep Ypresian clays (Ycs, 300 to 400 m below ground) since they are one of Belgium’s potential host rock formations for deep geological disposal of heat-emitting and long-lived radioactive waste. The impact o
