This course is the third part of the lecture series of Finite Element Analysis subject. It takes you through various topics like Basics Concepts of FEA, Various Concepts in FEA and Some Important Terminologies in FEA. Various concepts and their applications are explained which helps understanding the software used in FEA in depth and more easily. These topics help while solving of questions in ANSYS by manual calculation method and also help in understanding of ANSYS solutions. Basic Mathematics is the requirement for understanding of this subject.We start with Basics Concepts of FEA namely, Steps involved in FEA, Advantages of FEA, Disadvantages of FEA, Applications of FEA and Steps Involved in ANSYS Analysis. Further, we move to the Various Concepts in FEA namely, Sources of Error in FEA, Convergence in FEA, Element Types in FEA, Consistent and Lumped Mass Matrix in FEA, H-Method and P-Method in FEA, Shape Function and its importance, Isoparametric, subparametric and superparametric elements in FEA, Linear vs Non-Linear FEA, Difference between CFD and FEA, Axisymmetric Elements, Axisymmetric Element ANSYS Analysis, Concept of Serendipity in FEA, Advantages of Serendipity Elements in FEA, Equations of Elasticity and Significance of Material Properties in FEA.We also discuss the important terminologies used in FEA.
