The present study investigates the force transfer mechanisms for open hoop fiber reinforced plastic (FRP) strips attached at reinforced concrete (R/C) beams with or without anchorage. These open hoop FRP strips are utilized in R/C beams that are in need of shear capacity upgrade. This type of retrofitting is necessary for R/C structures designed with less stringent seismic loading conditions th...

and Implications A small demonstration sow herd has been housed during breeding and gestation in a deep-bedded hoop structure. Conception rates, number of pigs born alive, and birth weights were excellent. These results indicate that hoops provide a realistic alternative for housing gestating sows. A discussion of the decision considerations related to animal environment, sow behavior, bedding ...

A distributed Brillouin fiber sensor has been employed to detect localized pipe-wall buckling in an energy pipe by measuring the longitudinal and hoop strain distributions along the outer surface of the pipe for the first time. The locations of the localized pipe-wall buckling are found and distinguished using their corresponding strain-load data. The formation of the buckling process for the c...

The evergreen problem of a bead on a rotating hoop shows a multitude of bifurcations when the bead moves with friction. This motion is studied for different values of the damping coefficient and rotational speeds of the hoop. Phase portraits and trajectories corresponding to all different modes of motion of the bead are presented. They illustrate the rich dynamics associated with this simple sy...

This paper studies the relationship between height, volume and stress distribution in a superpressure pumpkin balloon with the differential pressure applied to the balloon. Two different approaches are presented. A simple two-dimensional solution based on previous work and a novel, detailed finite element simulation that provides three-dimensional solutions are investigated. It is found that th...

In this paper, the thermo-mechanical reliability of Cu/ultra low-k interconnects under chip to package interaction was investigated using finite element modeling and modified edge liftoff test (MELT). The crack propagation behavior in the low-k interconnect was simulated based on the crack tip opening displacement method (CTOD) and the maximum hoop stress criterion. In a six-level Cu/low-k inte...

Near a borehole, stress concentration effects may cause a complex spatial variation of elastic anisotropy. Stress-induced sonic anisotropy results when moduli and velocities are stress dependent and the state of stress is nonhydrostatic. For such cases, the appropriate material model is that of an elastic orthorhombic medium with material axes aligned with the principal axes of stress. We simul...
