Recently, there has been increasing researches on the McKibben type artificial muscle, because it is small, light, and high powered. In this study, in addition to the contraction artificial muscle, the stiffness change artificial muscle and the extending artificial muscle have been developed. By nonlinear finite element method analysis, the best sleeve knitting angle has been derived to achieve the stiffness change and the extension and contraction motions. From the results, three kinds of artificial muscles realizing contraction and extension motion, and the stiffness change have been fabricated. To apply high hydraulic pressure on the muscles, these are composed of the three layer tube and the reverse tapered plug. We confirmed that the three muscles respectively generate stiffness change, contraction, and extension motions successfully. In addition, the novel bending actuator has been developed by combining contractional and extensional artificial muscles. Bending motion with high stiffness has been realized.

This paper analyzed the cracking behavior of carbon fiber reinforced concrete beam under static load using the finite element numerical analysis. By the way of finite element numerical simulation and the method of increasing the load gradually to analyze the carbon fiber content influence on the beam cracking, crack developing, beam deflection and beam average crack spacing. By comparing with the simulation result of common reinforced concrete beam test piece, it turned out that the carbon fiber reinforced concrete beam has a good cracking and deformation behavior under the same ratio of reinforcement. Under the same load, both the carbon fiber reinforced concrete beam and the common reinforced concrete beam have a small deformation, but the carbon fiber reinforced concrete beam showed a better resistance to deformation as the load increasing, its deflection increasing extent showed an obvious decrease compared with that of the common reinforced concrete beams. Its crack width can be revised by the common reinforced concrete beam rules.
