Phononic crystals ( PCs) flexible mechanical arms are introduced to study the vibration characteristic. Two research models single PCs arm structure and two link PCs arm structure are considered . The finite periodic structures are established to describe the ideal PCs structure s . The finite element analysis shows that t he angle doesn’t influence the range of the band gaps BGs while it influences t he attenuation value of each BG T he more close to 90 degree gives more distinct BGs. For axial vibr ation s, the t wo link PCs arm structure has the advantage to enhanc e the attenuation effect..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
