A Study on Dynamics and Modeling Approach over Specifications

A concept of dynamics unifying engineering disciplines is put forward. A common expression of governing lows over different specifications as solid, fluid, electrical dynamics is presented. Two kinds of state values, namely flow value and potential value, are introduced as common state values over different engineering fields. New definitions of characteristics such as mass, stiffness, capacitance and inductance are proposed in a common manner directly based on energy theorem. A new approach of modeling is presented based on this dynamics
