Once the finite element matrix equations are solved for field values at the nodes, in postprocessing these derived quantities are graphically displayed. To know the variation of the field variable along the model/mesh contour plots of the field are plotted.The present code is useful for postprocessing of 2D and 3D finite element analysis. After finite element analysis is done for the nodal field values, the present code can be used to plot the...
Given assembeled mass, stiffness matrices and damping matrices, external load vector of n degree's of freedom, response of the system to the external load is calculated using Wilson tita step-by-step integration method. Time step, tita value can...
The plane stress problem i.e a plate under uniform tension at its edges is solved. Plate is dicretized using isoparametric Q4 elements. Pre-processing is done using a standard FEM software. 2nd order Gaussian integration is used to get stiffness...

These files calculate the natural frequencies and Euler buckling load using Finite element technique. Hermitian beam elements are used as interpolation functions. Assembled mass, geometric stiffness matrix and stiffness matrix are calculated and...
A thin plate under uniform transverse pressure is considered with simply supported and clamped boundary conditions. Using Finite Element Method plate equations are solved. Pre-processing is done using a standard FEM software. Plate is dicretized...
To discretize a plate using four noded elements. In plate bending (http://www.mathworks.in/matlabcentral/file...9-plate-bending) and in the plane stress problem (http://www.mathworks.in/matlabcentral/file...-stress-problem) I have used a FEM...
In the context of seismic analysis of structures, various earthquake inputs may be required depending upon the nature of analysis being carried out. The response spectrum of an earthquake is the most favored seismic input for earthquake engineers....
A nonlinear Simple Pendulum is simulated. Phase plane plot and time vs. displacement plots are updated accordingly. Pendulum equation is nonlinear, it is solved using ode45 of MATLAB. Mass, length, damping, and duration of pendulum can be changed.
The motion of a bead on a rotating hoop is simulated. A bead is sliding on a hoop rotating at certain angular frequency. It is interesting to study the motion of the bead.The equation of motion is nonlinear and is solved using ODE45 of the MATLAB.... |
