*Correspondence: Harsh Nayyar, Department of Botany, Panjab University, Chandigarh 160014, India e-mail: [email protected] Plants are exposed to a wide range of environmental conditions and one of the major forces that shape the structure and function of plants are temperature stresses, which include low and high temperature stresses and considered as major abiotic stresses for crop plant...

The significance of compressive thermal stresses generated during microwave heating on concrete surface delamination is investigated analytically in this paper. Microwave energy acts as an internal heating source that causes concrete to heat up. The amount of microwave energy dissipated in concrete depends on microwave frequency, microwave power and the electromagnetic properties of the concret...

The problem treated here is to determinethe viscosity effect on stresses, temperature change and chemical potential in a circular plate. The mathematical formulation is applied to two theories of thermoelastic diffusion developed by Sherief et al. [27] with one relaxation time and Kumar and Kansal [9]with two relaxation times. Laplace and Hankel transform techniques are used to obtain the expre...

Thermal effects on the pin-bearing behavior of an IM7/PETI5 composite laminate are studied comprehensively. A hypothesis presents factors influencing a change in pin-bearing strength with a change in temperature for a given joint design. The factors include the change in the state of residual cure stress, the material properties, and the fastener fit with a change in temperature. Experiments ar...

A range of abiotic environmental stresses results in H2O2 generation, from a variety of sources and it has many essential roles in plant metabolism but at the same time, accumulation related to virtually any environmental stress is potentially damaging. NO, another stress responsive molecule, is gaining high attention as a regulator of diverse physiological and biochemical processes in plant sc...

In this paper an e cient sequential approach for simulating thermal stresses in brake discs for repeated braking is presented. First a frictional heat analysis is performed by using an Eulerian formulation of the disc. Then, by using the temperature history from the rst step of the sequence, a plasticity analysis with temperature dependent material data is performed in order to determine the co...

The residual stresses in a TiN film deposited by a reactive ion coating process on a 316 stainless steel sheet were determined by the sin$ X-ray diffraction method, at temperatures from 15-800 “C. Using specially designed nickel clips, the coated strip was heated by the passage of a resistive current, in conjunction with a surround heater, and the temperature was measured by a Pt/Pt-lO%Rh therm...

This article deals with the determination of temperature distribution, displacement and thermal stresses of a rectangular plate having nonhomogeneous material properties with internal heat generation. The plate is subjected to sectional heating. All the material properties except Poisson’s ratio and density are assumed to be given by a simple power law along x direction. Solution of the two-dim...

ing from temperature gradients in a cylinder were derived by Duhamel (1838).‘ Since that time, about thirty papers have appeared which mainly consider the calculation of thermal stresses in an infinite cylinder subjected to temperature gradients. It is apparent that thermal stresses are not a new or uninvestigated phenomenon. The first quantitative treatment of thermal stress fracture in cerami...

The present study aims to investigate the residual stresses and surface hardening in ground components caused by the coupled effect of thermo-plasticity and phase transformation. A feasible numerical method was developed to accommodate appropriately the phase transformation in a workpiece experiencing critical temperature variation during grinding. The change of material properties was modelled...
