FEM is a numerical method of solving engineering and mathematical problems.Stress Analysis for trusses,beams and other simple structures are carried out based on dramatic simplification and idealization.

Types of Finite Elements

1-D Line Elements – Spring,truss,beam etc

2-D Plane Elements – plate , thin shell, thick shell, membrane etc

3-D Solid Elements – 3D quadratic element etc

Important Basic keywords in FEM

Element , Nodes, Displacement, Stress , Strain ,Shape functions,Degree of freedoms, translations,rotations, stiffness matrix

formulation of each element and application of these elements are discussed in this blog.
