Abstract AR
هذا البحث يقدم التطبيق لنظرية (Higher Order Shear Deformation Theory (HOST 12)) لمسألة الاهتزاز الحر للصفائح الطبقية المركبة المتماثلة و الغير متماثلة (ذات الألياف الغير متعامدة).
النظرية المقدمة HOST 12 تدج تشويهات الطبقات التي تفسر تأثيرات تشويه القص المستعرض، إجهاد طبيعي مستعرض / إجهاد و التوزيع اللاخطي لأزاحات المستوى بالنسبة للسمك-هكذا تشكل تشويه المقاطع العرضية المستعرضة بدقة أكثر و تزيل الحاجة لمعاملات تصحيح القص.
الحلول للمعادلات تضمنت الحل المضبوط للصفائح الطبقية المركبة (Navier Solution).
أخذ بالاعتبار تأثير تنويع مواصفات الصفائح كعدد الطبقات و درجة الأنتروبي و نسبة السمك إلى العرض.
النتائج قورنت مع حلول مضبوطة و نظريات متنوعة من مصادر متعددة.
Abstract EN
This paper presents an application of a Higher Order Shear Deformation Theory (HOST 12) to problem of free vibration of simply supported symmetric and antisymmetric angle-ply composite laminated plates.
The theoretical model HOST12 presented incorporates laminate deformations which account for the effects of transverse shear deformation, transverse normal strain/stress and a nonlinear variation of in-plane displacements with respect to the thickness coordinate – thus modeling the warping of transverse cross-sections more accurately and eliminating the need for shear correction coefficients.
Solutions are obtained in closed-form using Navier’s technique by solving the eigenvalue equation.
Plates with varying number of layers, degrees of anisotropy and slenderness ratios are considered for analysis.
The results compared with those from exact analysis and various theories from references.
