AS4009 Theory of Plates and Shells Syllabus – Anna University PG Syllabus Regulation 2021

COURSE OBJECTIVE

To get fundamental understanding of the classical theory of elastic plates and shells, address limitations and differences, nomenclature, analytical and numerical solution techniques. To enable students to apply the theory of plates to problems, involving various geometries and boundary conditions, to diverse problems in aerospace engineering.

UNIT I THEORY OF PLATE BENDING

Plate-Bending Theory – Classical Solution Methods-Rectangular Plates, Circular Plates – Plates on Elastic Foundations

UNIT II ENERGY METHODS

Analysis of Membranes-Bending & Stretching- Ritz Method- Galerkin’s method- Finite Difference method- Large Deflection – Stability: Fundamentals, Applications

UNIT III VIBRATIONS AND STABILITY OF PLATES

Stability and Free Vibration Analysis of Rectangular Plates with various end conditions.- nonlinear geometric effects- Free Vibration and Stability Analysis.

UNIT IV SHELLS

Basic Concepts of Shell Type of Structures – Membrane and Bending Theories for Circular Cylindrical Shells – the general theory of elastic shells and axisymmetric shells – Introduction to the nonlinear analysis of shells.

UNIT V BUCKLING OF SHELLS

buckling, crushing and bending strength of cylindrical shells – Energy absorption and crashworthiness of prismatic tubes – Applications: Pipes, Tanks, Pressure Vessels

TOTAL: 45 PERIODS
