WebThe element stiffness matrix is defined over the element Ω(e). The integration domain for Eq. (7.117a) can be interchanged as follows, d Ω (e) = t dA. As the integration is expressed in the generalized coordinate system, we also have the following relationship, dA = J dξdη. Thus Eq. (7.117a) becomes, (7.118) WebFor an undamped system, the matrix equation of motion always looks like this where x is a vector of the variables describing the motion, M is called the ‘mass matrix’ and K is called …
