In this section, we will present a MATLAB code for bending analysis of composite plates using CLT and FEA. The code will calculate the deflection, slope, and stresses of a composite plate under a point load. % Define load P = 100; % point
The bending analysis of composite plates involves determining the deflection, slope, and stresses of the plate under various loads, such as point loads, line loads, or distributed loads. The analysis can be performed using analytical methods, such as classical laminate theory (CLT), or numerical methods, such as finite element analysis (FEA). The analysis can be performed using analytical methods,
