I'm doing an research about a cantilever which can undergoes large rotations along two directions. At the head of the cantilever there is a magnetic particle. When I establish the dynamic model for this cantilever, I just consider the mass of the particle(since the mass of the beam is small). However after I obtian the mass matrix (6 by 6, six DOFs), i found it is not symmetric. I don't know the reason. Can anyone help me? By the way, if the beam undergoes large rotation, will the stiffness matrix(tangent matrix) at each state keep symmetric ? Thank you
