【Abstract】

<正>A large deflection model is proposed to study light-induced bending of liquid crystal elastomers(LCEs).The equations for in-plane membrane force and deflection with geometrical nonlinearity are derived by using Hamilton principle.The effect of light is defined as an effective optical bending moment generated by inhomogeneous light-induced strain and the membrane forces.Solving the coupled equations can give the deflection curves of LCEs under any boundary conditions and illumination.As examples,
