The Transient Response of Flat Plates Using the Finite Element Method
In the finite element method a discrete system is derived to approximate a continuum. A discretizing method is justified for this investigation by comparing the dynamic analysis of a discrete system with that of a plate continuum using the variational calculus. The transient response of the former …

Strength and Performance of Steel Fiber Reinforced Concrete Post-Tensioned Flat Plates
… steel fiber reinforced concrete post-tensioned flat plate. The specimen had nine 10ft x 10ft x 3in. bays along with a 2ft-6in. overhang. Distributed loading was applied with a whiffle tree loading system at each bay and overhang section. Throughout the test, crack widths, crack locations, …

Performance of Steel Fiber Reinforced and Conventionally Reinforced Post-Tensioned Flat Plates
… and residential buildings, post-tensioned (PT) flat plates have become a preferred choice for floor systems, because of the numerous advantages over non-prestressed slabs such as better efficiency, reduced slab self-weight, as well as crack and deflection control. To improve the competitive …

The effect of surface wettability on frost growth and densification on flat plates
… frost growth and densification rates on cold, flat surfaces subject to forced convective heat and mass transfer depend on surface wettability and cooling rate during the condensation phase. If the cooling rate is high during the condensation phase, then the droplet distribution at incipient …

An investigation of methods for determining notch root stress from far field strain in notched flat plates.
Notched flat plate specimens have been tested to examine Neuber's equation and other relations with respect to their application in the determination of stresses in the plastic range at the notch root when the far field strain is known. A nonlinear finite element solution has also been obtained for …

An investigation into the effect of longitudinal micro-striations and their profiles, on the drag of flat plates
… of reducing the drag force experienced by a flat plate. V-grooves of specific dimensions are machined onto the surface of a smooth plate, in a streamwise direction. The effect of these surface modifications on the drag force of a smooth plate is examined. The use of surface modifications as a …

Numerical and Experimental Studies of Natural Convective Heat Transfer From Vertical and Inclined Narrow Flat Plates and Short Cylinders
Natural convective heat transfer from flat plates and short cylinders inclined at an angle to the vertical in laminar and transition flow regions with isothermal or constant heat flux conditions have been numerically and experimentally studied. When the width of the plate is relatively small …
