AZOM: Modulus of Elasticity and Poisson's Ratio of Concrete in Compression by ADMET
This video by ADMET shows a concrete compression test performed according to ASTM C469 - Standard Test Method for Static Modulus of Elasticity and Poisson's Ratio of Concrete in Compression.
Modulus of Elasticity and Poisson's Ratio of Concrete in Compression by ADMET
If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...
An understanding of a material's microscopic architecture is important to improve its mechanical properties. Poisson's ratio, which celebrates its bicentenary this year, continues to provide a good ...
1 I will give an intuitive explanation, only needing the defining properties of the Poisson Process and the exponential distribution, without needing any calculations involving densities. In short, the Poisson Process having independent and stationary increments and the exponential distribution being memoryless explains this connection:
If two events occur at a rate of 1.8 per hour on average, and this occurrence follows a poisson process, what is the probability that there is at least 1 hour between two events? My approach for t...
Finding the probability of time between two events for a poisson process
The criteria in your book are for interval data; that would be useful if you had the dates at which hurricanes stroke... moreover these criteria are for constant rate Poisson processes, which is obviously (or I hope so) not the case of hurricanes. To check if your count data follow a Poisson distribution, a first elementary approach is the chi-square test.
