2D Elasticity - Q4 Finite Element Solver

A FEM code for solving linear, static, 2D plane stress elasticity problems using Q4 elements.

A finite element analysis computer program for solving linear, static, 2D plane stress elasticity problems using isoparametric elements with 4 nodes per element is developed. The loads are restricted with 2D point forces. The boundary conditions are restricted to homogeneous displacement boundary conditions to be applied on nodes.
The program mainly focuses on the ‘solver’ part of any modern Finite Element Package, however, some pre-processing and post-processing utility programs, simply for basic mesh generation, or displaying resulting stress, strain or displacement fields are also developed as required.
All inputs and physical calculations are performed for metric units. All the results presented are also in metric unis, unless otherwise stated.
- Positions, Displacements: meter (m)
- Forces: Newton (N)
- Pressures, Stresses, Young Modulus: Pascal (Pa)
