| 2 | Electromechanical buckling behavior of smart piezoelectrically actuated higher-order size-dependent graded nanoscale beams in thermal environment显示文摘In the present work,thermo-electro-mechanical buckling behavior of functionally graded piezoelectric(FGP)nanobeams is investi-gated based on higher-order shear deformation beam theory.The FGP nanobeam is subjected to four types of thermal loading including uniform,linear,and sinusoidal temperature rise as well as heat conduction through the beam thickness.Thermo-electro-mechanical properties of FGP nanobeam are supposed to change continuously in the thickness direction based on power-law model.To consider the influences of small-scale sizes,Eringen’s nonlocal elasticity theory is adopted.Applying Hamilton’s princi-ple,the nonlocal governing equations of an FGP nanobeam in thermal environments are obtained and are solved using Navier-type analytical solution.The significance of various parameters,such as thermal loadings,external electric voltage,power-law index,nonlocal parameter,and slenderness ratio on thermal buck-ling response of size-dependent FGP nanobeams is investigated. | Farzad Ebrahimi Mohammad Reza Barati | 2016 | International Journal of Smart and Nano Materials2016,7,2: | 2 |
| 3 | Temperature distribution effects on buckling behavior of smart heterogeneous nanosize plates based on nonlocal four-variable refined plate theory显示文摘This work presents a theoretical study for thermo-mechanical buckling of size-dependent magneto-electro-thermo-elastic func-tionally graded(METE-FG)nanoplates in thermal environments based on a refined trigonometric plate theory.Temperature field has uniform,linear,and nonlinear distributions across the thick-ness.Nonlinear thermal loadings are considered as heat conduc-tion(HC)and sinusoidal temperature rise(STR).A power law function is applied to govern the gradation of material properties through the nanoplate thickness.Considering coupling impacts between magneto,electro,thermo-mechanical loadings,the equa-tions of motion,and distribution of magneto-electrical field across the thickness direction of the METE-FG nanoplate are derived.The exact solutions for critical buckling temperatures of METE-FG nanoplates are introduced implementing Navier’s method.Moreover,the accuracy of the present formulation is examined by comparing the obtained results with published ones.Furthermore,the effects played by the magneto-electrical field,various temperature rises,nonlocality,power law index,side-to-thickness ratio,and aspect ratio on the critical buckling tempera-ture response are all investigated and reported. | Farzad Ebrahimi Mohammad Reza Barati | 2016 | International Journal of Smart and Nano Materials2016,7,3: | 1 |

| 10 | Thermal Buckling Analysis of Size-Dependent FG Nanobeams Based on the Third-Order Shear Deformation Beam Theory显示文摘In this paper,the thermal effects on the buckling of functionally graded(FG) nanobeams subjected to various types of thermal loading including uniform,linear and non-linear temperature changes are investigated based on the nonlocal third-order shear deformation beam theory.The material properties of FG nanobeam are supposed to vary gradually along the thickness direction according to the power-law form.The governing equations are derived through Hamilton's principle and solved analytically.Comparison examples are performed to verify the present results.Obtained results are presented for thermal buckling analysis of FG nanobeams such as the effects of the power-law index,nonlocal parameter,slenderness ratio and thermal loading in detail. | Farzad Ebrahimi Mohammad Reza Barati | 2016 | Acta Mechanica Solida Sinica2016,29,5: | 0 |
| 11 | Carpet Cloak Design for Rough Surfaces显示文摘Conventional carpet cloak structures have been utilized to conceal the objects located on a planar perfect electric conductor surface. We systematically investigate hiding arbitrarily shaped objects on a rough surface, as a more general and practical scenario. In addition, the required cloak is designed considering different boundary conditions for the surface beneath the object, despite the previous studies. To achieve an invisibility cloak, taking advantage of linear coordinate transformation, a simple homogeneous material is obtained to realize the cloak structure, facilitating the fabrication processes. Numerical simulations validate the performance of the proposed cloaking method. Therefore, the proposed structure is capable of cloaking in more general and complicated scenarios. | Mohammad Hosein Fakheri Hooman Barati Ali Abdolali | 2017 | Chinese Physics Letters2017,34,8: | 0 |

| 13 | Evaluation of the Relationship between Blocking Patterns and Duration of Spring Frost Waves:The Case of Iran显示文摘In order to evaluate the effects of blocking patterns on the duration of frost waves across Iran,the minimum daily temperatures of 60 weather stations were collected from 20 March 1968 to 21 June 2014.The findings,which were obtained based on the distribution tables of reported temperatures and their frequency variation graphs,resulted in identifying 114 frost waves.We obtained the daily weather maps at 500 hPa from NCEP/NCAR during the peak days of durable frosts,and it was revealed that the formation of low pressures over 20°-70°E and the dominant southwest-northeast troughs at 500 hPa facilitated the influx of cold air from both eastern Europe and central Siberia toward Iran,leading to the average frost duration of 12.4 days.Furthermore,low-pressure centers appeared in a dipole pattern in northern Iran over Caspian Sea and created durable frosts with an average duration of 15.4 days.The effect of omega shaped pattern of the geopotential height on durable frosts demonstrated a sharp difference with two recent patterns leading to the frost occurrence with a 13.3-day duration averagely.Additionally,the slow speed of cold western currents in the rex type of blocking from 30°to 50°N caused durable frosts of 14.3 days.Also,we found a specific reduction in the frequency of blocking patterns,which has occurred in the past four decades.Mostly,the blocking and non-blocking patterns cause long-and short-duration frosts over Iran,respectively. | Farzaneh JAFARI HOMBARI Gholamreaza BARATI Mohammad MORADI | 2020 | Journal of Meteorological Research2020,34,3: | 0 |
