The code is based on Finite Element Method with Hermitian shape functions.
The interested reader can find the theory behind this simulation on my Academia page https://independent.academia.edu/AndreaLaSpina.
The script allows you to choose all the geometric properties as well as the FEM parameters, like the number of finite elements, the number of Gauss integration points, the boundary and the initial conditions.
The time integration is performed through the Matlab ode45 solver based on the Dormant-Prince formula.
The analysis is linear and a Rayleigh damping can be taken into account.
The results are shown in many nice plots and an energetic balance validates also the accuracy of the analysis.
