Force density

Force density is a physical concept often used in fields like physics and engineering, particularly in the context of continuum mechanics and material science. It is defined as the force per unit volume applied to a material or system. In mathematical terms, force density \(\mathbf{f}\) is expressed as: \[ \mathbf{f} = \frac{\mathbf{F}}{V} \] where \(\mathbf{F}\) is the total force acting on the volume \(V\).
