Besides the three main categories of bistable mechanisms such as latch-lock mechanisms, hinged multisegment mechanisms, and residual-compressive-stress buckled beams, a novel unsymmetrical bistable mechanism with a combined structure of permanent magnets and mechanical beams is proposed, and the bistability of such combined structure is analyzed based on the magnetic-charge model and material mechanics theory.
Based on the theory of material mechanics [10] and the beam boundary conditions, the stiffness of the elastic beam k can be obtained as follows
The bistability of such bistable structure is analyzed based on the magnetic-charge model and material mechanics theory.

Introduction Titanium dioxide (TiO2) is one of the most promising materials widely applied in fields involving environmental purification and decomposition of pollutants, photocatalyst and self cleaning coating, water splitting catalysts for hydrogen generation, gas sensing elements, electrode materials for dye - sensitizing solar battery and energy production and storage [1-4].
Recently, many low dimensional TiO2 materials, such as nanowires, nanotubes and nanorods have been successively synthesized.
Consequently, these materials can be further used in the fields involving photocatalyst, gas sensing elements and selective adsorption materials.

Study on the Low Cycle Fatigue Damage of Nodular Cast Iron Based on Elastic Modulus Jinhai Liu1,a, Xiaoyan Hao1,b , Guolu Li1,c , Xuebo Zhao 1,d and Gensheng Liu1,e 1 School of Materials Science and Engineering, Hebei University of Technology, Tianjin 300132, China.
The damage mechanics suggested that the damage is an internal variable affecting the strength of materials.
According to the definition of damage variable, there are several methods to measure the damage of materials.
Because of different damage mechanism in the materials with different microstructure, the methods to detect sensitively the damage of materials are various.
As we know, at the early cycle stage, the metallurgical structure of materials is at unstable state.
