Calculating member forces using stiffness matrix in 2 Dimension PART 1 of 2 - Finite Element Methods
In this video I use the local stiffness matrices to calculate the internal forces within each member. ITS SIMPLE! STEP 1 Using the local stiffness matrices, equate the Force vector to the product of the stiffness matrices and the displacement vector. STEP 2 perform matrix multiplication and solve for the unknown forces of interest. STEP 3 Repeat with each member and the corresponding local stiffness matrix. STEP 4 Calculate the RESULTANT force for each member using the fx and fy component.
