Inverse Dynamics is used to calculate the forces and moments in joints of multibody systems investigated fields such as Biomechanics or Robotics. In a didactic spirit, this paper begins with an overview derivations kinematical dynamical equations rigid bodies from point view modern Continuum Mechanics. Then, it introduces matrix formulation for solution problems and, finally, reports simple two...

In mechanics, linear models have been well developed and received wide acceptance. They are based on linear elasticity, incompressibility of fluids and ideal gas properties. At the present stage of scientific and technical advances very exacting requirements are imposed upon materials and structures. The necessity to take into account their properties in nonlinear area of the mechanical behavio...

abstract background: the prevalence of disordered eating behaviors has been reported to increase in recent decades; therefore, the search for specific psychological variables that may contribute to the etiology of this disorder is of great importance. the current study examined the mediating role of the emotion regulation difficulties on the relationship between body image disturbance and disor...

Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...

This study investigates propagation of mode I crack in B70 pre-stressed concrete sleepers by fracture mechanics approach. A new experimental analysis is done for notched B70 pre-stressed concrete sleepers with Replica test and image analysis. A scanning electron microscope test (SEM) and an image analysis are applied for the Replica test in order to determine crack length and crack mouth openin...

Casing collapse is one of the major problems in oil fields, imposing a lot of costs on oil companies. This problem occurs not only at drilling times in some formations but also after the completion and production can lead to many problems. Analysis of the behavior of casing collapse in terms of geo-mechanics and solid mechanics could significantly meet the needs of the oil industry of Iran. In ...
