This study evaluated kinematic, vertical ground reaction forces, and strength variables in healthy collegiate female basketball, volleyball, and soccer players compared with matched male subjects. Thirty athletes did single-leg landing and forward hop tasks. An electromagnetic tracking device synchronized with a force plate provided kinematic data and vertical ground reaction force data, respec...

Some structural control systems have been devised to protect structures against earthquakes, which the tuned mass damper (TMD) being one of the earliest. The effect of a tuned mass damper depends on its properties, such as mass, damping coefficient, and stiffness. The parameters of tuned mass dampers need to be tuned based on the main system and applied load. In most of the papers, the paramete...

This study examines the relationship between shear force and horizontal relative displacement of Lshape shear connector by means of beam type test method. An equation for maximum shear force of the specimen which takes into account the effects of size of the shear connector and the concrete strength was proposed. It was found that shear force-horizontal relative displacement relationship can be...

Introduction: Internal derangement (ID) of TMJ is the most common type of temporomandibular disorders after muscle disorders and includes all disorders related to incoordination and dislocation of disc and condyle. Anterior disc displacement without reduction or closed lock will happen if the disc or condyle displaces severely or if the disc traps in the space in front of the condyle accompanie...

PURPOSE The purpose of this study was to investigate the effects of implant tilting and the loading direction on the displacement and micromotion (relative displacement between the implant and bone) of immediately loaded implants by in vitro experiments and finite element analysis (FEA). METHODS Six artificial bone blocks were prepared. Six screw-type implants with a length of 10 mm and diame...

Mechanical behavior of two-layer metal laminate structures under low-speed impact loading was investigated experimentally and numerically. The experimental results were just used for validation of numerical results. Then numerical modeling was used to study the behavior of metal laminates in details. The mechanical behavior of the metal laminate structures under impact loading was found to be d...

We study the transient drag force FD on a localized intruder in a granular medium composed of spherical glass particles. A flat plate is translated horizontally from rest through the granular medium to observe how FD varies as a function of the medium's initial volume fraction, ϕ. The force response of the granular material differs above and below the granular critical state, ϕc, the volume fra...
