Increased emotional distress is linked to greater physiological reactions. During relationship conflict, these physiological reactions impact each partner’s physiological and physical well being. This emotional and physiological disturbance has been seen in direct relationship conflicts. Even though the aspect of the conflict that these disturbances are linked to creates physiological reaction,...

In this paper, the free vibration analysis of sandwich micro beam with piezoelectric layers based on the modified couple stress and surface elasticity theories are investigated. The Hamilton’s principle is employed to derive the sandwich micro beam with piezoelectric based on modified couple stress theory incorporating with Gurtin- Murdoch surface theory. The generalized differential quadrature...

The purpose of this study was to compare of the effectiveness of emotion-focused couple therapy and mindfulness-based stress reduction program on the emotional divorce of couples. This semi-experimental study was conducted with a pretest-posttest design with a control group and follow-up for two months. The statistical population included all the couples referring to counseling and psychologica...

In the present paper is concerned with study of thermoelastic interaction in an infinite KelvinVoigt type viscoelastic, thermally conducting solid bordered with viscous liquid half-spaces/layers of varying temperature. Complex secular equations in closed and isolated mathematical conditions for Rayleigh wave propagation in completely separate terms are derived. The results for coupled and uncou...

In this paper, the surface waves propagation in a generalized magneto-thermoelastic materials taking (Green Lindsay) model with voids and initial stress is investigated. The basic governing equations have been formulated in xz-plane and the magnetic field is considered in y-axis that acts perpendicular to the wave propagation. Lame's potential method is applied to solve the problem. The boundar...

Structural components subjected to high frequency vibrations, such as those used in vibrating parts of gas turbine engines, are usually required to avoid resonance frequencies. Generally, the operating frequency is designed at more than resonance frequencies. When a vibrating structure starts or stops, the structure has to pass through a resonance frequency, which results in large stress concen...

In a recently developed model of ion beam induced plastic deformation of amorphous solids, ion tracks are described as cylindrical thermoelastic inclusions formed upon local heating and shear stress relaxation along the ion trajectories. According to this model, track formation can be influenced or even suppressed by an applied stress. This model prediction is tested by studying the influence o...

Abstract Background The Stress Intensity Factor (SIF) is used to describe the stress state and mechanical behaviour of a material in presence cracks. SIF can be experimentally assessed using contactless techniques such as Thermoelastic Analysis (TSA). classic TSA theory concerns relationship between temperature variations was successfully applied fracture mechanics for evaluation crack tip loca...

In the present article, a comprehensive review of relevant literature is presented to highlight the role of fractional calculus in the field of thermoelasticity. This review is devoted to the generalizations of the classical heat conduction equation and formulation of associated theories of fractional thermoelasticity. The recently developed fractional order thermoelastic models are described w...
