In this paper, we present an effectively numerical approach based on isogeometric analysis (IGA) and higher-order shear deformation theory (HSDT) for geometrically nonlinear analysis of laminated composite plates. The HSDT allows us to approximate displacement field that ensures by itself the realistic shear strain energy part without shear correction factors. IGA utilizing basis functions name...
A novel and effective formulation that combines the eXtended IsoGeometric Approach (XIGA) and Higher-order Shear Deformation Theory (HSDT) is proposed to study the free vibration of cracked Functionally Graded Material (FGM) plates. Herein, the general HSDT model with five unknown variables per node is applied for calculating the stiffness matrix without needing Shear Correction Factor (SCF). I...

Due to its faster implementation and potential cost savings for estimating the bearing capacity of PHC pipe piles, High Strain Dynamic Test (HSDT) offers an alternative approach Static Load (SLT). The report presents a study via those methods with sliding micrometer. And Pile Driving Analyzer (PDA) imported from United States is employed, determine design parameters pile foundation engineering ...
The present study introduces a generalized 2-unknown’s higher order shear deformation theory (HSDT) for isotropic and orthotropic plates. The well-known Shimpi’s two-unknown's HSDT is reproduced as a special case. Reddy’s shear strain shape function (SSSF) is also adapted to the present generalized theory. The results show that both Shimpi and the adapted Reddy’ HSDT are essentially the same, i...
در این مقاله به منظور تحلیل الاستیک پوستههای استوانهای تشکیل شده از مواد هدفمند (fgm)، معادلات دیفرانسیل حاکم بر استوانههای جدارضخیم چرخان fgm تحت فشار در حالت متقارن محوری به کمک تئوری تغییر شکل برشی مرتبه سوم (tsdt) استخراج و حلّ عمومی آنها برای شرایط انتهایی دو سرگیردار ارائه شده است. سپس با انجام مطالعه موردی و همچنین ارائه یک حلّ عددی، توزیع جابهجایی و تنش حاصل از حلّ تحلیلی به کمک تئور...
Free vibration of laminated composite shells with cutouts are presented by a nine noded curved C0 finite element (FE) formulation developed by authors based on higher order shear deformation theory (HSDT) using Sander's approximations. The proposed model satisfies parabolic distribution of transverse shear strains through the shell thickness and zero transverse shear stress conditions at shell ...
This paper presents a thermoelastic bending analysis of functionally graded sandwich plates by using a new quasi-3D hybrid type higher order shear deformation theory (HSDT). The mathematical model contains only 5 unknowns as the first order shear deformation theory (FSDT). The nonlinear term of the temperature field is modeled in such way that can be different from the shape functions of the di...
