Diameter Distributions of Juvenile Stands of Loblolly Pine (Pinus taeda L.) with Different Planting Densities
… densities were characterized utilizing a two-parameter Weibull distribution. Trend analysis was employed to describe the effects of planting density, age, relative spacing, and rectangularity on the estimated diameter distributions for juvenile loblolly pine. A reparameterization of the …

A stochastic model of component failure mechanisms
… the failure model can be described as a three-parameter or two-parameter Weibull distribution.

The Effects of Carbon Fiber Misalignment on Composite Material Strength
… of unidirectional carbon fiber samples. A two parameter Weibull distribution is expected to satisfy the probability density of the fiber length and fiber orientation variation which will then be implemented into the Halpin-Tsai equations that will determine the elastic modulus. In terms of …

MODELING DIAMETER DISTRIBUTION OF LOBLOLLY PINE PLANTATIONS IN RESPONSE TO MID-ROTATION THINNING TREATMENTS AND ASSING THE ECONOMIC RETURNS IN WESTERN GULF COASTAL PLAIN
… across East Texas and Western Louisiana. A two-parameter Weibull distribution was used to model diameter distributions under varying thinning intensities, with parameter estimation conducted using both parameter prediction (PPM) and percentile-based (PRM) methods. The PRM approach …

Dynamics and failure analysis of architectural glazing subjected to blast loading
… architectural glazing. Use of laminated glass, two soda lime glass plies are adhered to a polyvinyl butyral (PVB) interlayer, has the potential for limiting such hazards. Most of the work on laminated glazing subjected to blast loading has been experimental and primarily geared towards product …

Crush Strength Analysis of Hollow Glass Microspheres
… a major factor affecting strength as well as the Weibull parameters. Two different methods, microscopy counting and laser light scattering, used in the research yielded similar distributions. The main objective of this research was to analyze the crush strength of individual microspheres. Using …

Simulation of Early Stand Development in Intensively Managed Loblolly Pine Plantations
… Annual height growth is predicted using a two-parameter Weibull function, where distribution parameters are estimated from equations that utilize site index and age as predictor variables. Allometric equations are employed to estimate tree diameter and height-to-crown attributes. First year …

Analysis of laminated architectural glazing subjected to combined wind and debris impact loading
… like hurricane. Laminated glass is composed of two glass layers with a polymer as an interlayer. The main objective of this work involves studying the stress response, failure and damage analysis of rectangular laminated architectural glazing against combined wind and windborne debris impact. …

Mechanical characterization of advanced polyacrylonitrile derived carbon fibers reinforced with carbon nanotubes
… for a large number of individual fibers. The two parameter Weibull distribution was used to analyze the mechanical strength data. Due to variability in the fiber cross-section and the two different gauge lengths, a volume corrected Weibull analysis was applied. Fibers isolated from three …
