The purpose of this study is to identify the leading causes slope instability along a local highway in Anhui, People’s Republic China. As part east expansion project, mountain range will be excavated create two-way, nearly 30 m wide highway. site’s topography consists hill with palm-shaped faces carved from limestone running its sides. geological characteristics and stability research area high...

A mode II mechanical characterisation of the adhesive joints is performed testing shear lap joint specimens in a Split Hopkinson Tensile Bar (SHTB), equipped with temperature chamber. The experimentallyobtained traction-separation curves were used to develop Cohesive Zone Model (CZM) capable representing strain-rate and temperaturedependent response joints. To validate model, End Notch Flexure ...

By studying the physics behind toppling dominoes we are able to create a theory to predict the time for the dominoes to fall and if necessary, find an arrangement of dominoes that will optimize the topple time. The conservation of energy is used and all interactions between the dominoes are neglected except for the initial impact. Using the number of dominoes, the geometry of the chain, and the...

Straightening of a cranial base flexure observed in the midsagittal presphenoid region of mice has been postulated to play a major role in palate closure by providing the internal shelf force for palatal shelf movement. The straightening is thought to take place during the 8 h immediately preceding closure. This mechanical model assumes that straightening of the cranial base flexure is transmit...

Robot manipulators having elastic links or flexure joints have a number of advantages, especially in simplifying the control of contact with other objects. However, current simplified parametric models of flexure motion do not accurately predict the behavior of these mechanisms under large deflections. This paper presents a “smooth curvature model” of flexure behavior that describes the curvatu...

In this paper, we propose a 2-DOF parallel mechanism with flexure hinges. The kinematics and static analyses of this mechanism are studied in order to determine the kinematics properties, workspace, holding forces of the actuators and the reaction forces at the flexure hinges. These factors are useful for design process of this mechanism. The pseudo-rigid-body model (PRB model) of this mechanis...

OBJECTIVE When successive restorative procedures (e.g., porcelain veneers, interdental resin composite restorations, and endodontic treatment) are carried out on the same tooth, significant effects on crown flexure can be expected. METHOD AND MATERIALS Dentin-bonded porcelain veneers (experimental group) were assessed in vitro using functional and cyclic thermal loads. They were compared to n...
