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. The residual stresses due to solid therm

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. These additional factors significantly affect the ada

Abstract:

This paper demonstrates a novel Eulerian computational framework for modeling anisotropic elastoplastic deformations of organic crystalline energetic materials (EM) under shocks. While Eulerian formulations are advantageous for handling large deformations, constitutive laws in such formulations have been limited to isotropic elastoplastic models, which may not fully capture the shock response of crystalline EM. The present Eulerian framework for high-strain rates, large deformation material dynamics of EM incorporates anisotropic isochoric elasticity via a hypo-elastic constitutive law and vis

Abstract Synthetic ropes are increasingly being considered for various offshore and marine applications, including for mooring offshore wind turbines and for aquaculture cages. Studies have shown that nonlinear behaviors of a synthetic rope in a dynamic environment can complicate the mooring system analysis. Nonlinear stiffness coupled with time- and load history-dependent characteristics of fibrous materials can allow for over or under estimation of the mooring forces. It is critical that these nonlinear properties are incorporated correctly into a mooring model, especially for studies of str

In an effort to maximize efficiency and decrease emissions, modern gas turbine combustors are exposed to extreme operating conditions which if not accounted for during the design process, can lead to premature failure of the combustion components. Of interest to this article are some operating conditions that, in many instances can expose the gas turbine combustion chambers (liners) to asymmetric thermal loads. Highly asymmetric thermal loads at high temperatures can inflict severe distress on combustion liners attributing to thermal creep distortion and Thermo-Mechanical Fatigue (TMF). Modern

Arc-welding involves the deposition of molten filler metal and the localised input of intense heat. The surrounding parent material and, in the case of multi-pass welds, previously deposited weld metal, undergoes complex thermo-mechanical cycles involving elastic, plastic, creep and viscous deformations. These processes result in the development of large residual stress gradients around the welded region, which can be particularly detrimental to the structural integrity of plant components.

We performed three loading and unloading stages on each sample, measuring time-dependent deformation after each stage. For two samples, we started at room temperature (24 °C), then increased temperature to 50 °C and then from 50°C to 80°C. We reported that the elevated temperatures soften the samples and increase the creep deformation rate. However, the creep behavior of the sample under a cyclic loading pattern and at a constantly elevated reservoir temperature is s

Mechanical deformations were measured using bulk solder tensile specimens and grooved lap shear specimens which enabled a stress-state of nearly pure shear in the solder joint.

Therefore, the plastic deformation of dies made of four different tool materials was investigated in the present study.

In high-rate failure models for geological and rock-like materials, heating due to inelastic deformation is often neglected or accommodated incompletely through the use of an isentropic elastic response. However, for realistic prediction of geomaterials response to high-rate large deformations with significant released energy (such as buried explosive), dissipation caused by the initial mechanical work of the blast wave results in a non-negligible entropy generation that must be accounted for in constitutive modeling.
