Waves on Elastic Rods and Helical Spring Problems
… curvature and torsion, i.e. a straight rod and a helical rod. The first set of problems concerns planar traveling loop-like waves on intrinsically straight rods. It is shown that loops with compact support can exist on homogeneous rods with a nonlinear constitutive relation, where the …

Compliant Mechanisms to Perform Bearing and Spring Function in High Precision Applications
… of traditional elements such as bearings and springs is limited. The backlash of bearings also limits their usefulness in applications where high precision and repeatability are needed. At small scales and for high precision applications, alternative, non-traditional elements are needed.</p> …

Large Deflections of Helical Springs
The problem analyzed is that of a helical spring subjected to end couples and forces which produce large deflections of the spring. These deflections are such that the angle of rotation of one end of the spring centerline with respect to the other end of the spring centerline exceeds the range …

The Development of Actuators for the Whole Skin Locomotion Robot
… design limits are established. In addition, a helical spring backbone design is considered and stiffness properties for general helical springs are determined. The contact of spring coils is included in the analysis and a coupled constitutive model is developed for the spring when coils are in …

Mechanical behavior and environmental stability of GLAD-based Cu nanospring films
Glancing Angle Deposition (GLAD) based Cu nanospring films are a promising form of film that combines high electrical and thermal conductivities with robust mechanical performance. This dissertation research focuses on quantifying the mechanical performance and environmental stability of GLAD-based …

Mechanical behavior of nanostructured metallic films under compressive and shear loads
… thin films consisting of arrays of Cu and Ag helical springs. Rectangular areas of films were loaded in uniform compression and shear and the film properties were obtained through the load versus displacement response. The compressive stiffness of the nanostructured Cu films was measured to be …

Stiffness Model of a Die Spring
… stiffness matrix of a rectangular cross-section helical coil compression spring. The stiffnesses of the spring are derived using strain energy methods and Castigliano's second theorem. A theoretical model is developed and presented in order to describe the various steps undertaken to calculate …
