relevant equations for strength test

Development of Regression Equations to Predict C.B.R of

resulted in the development of correlation equations, suitable only for a set of soils. CBR being a measure of strength of soils, it becomes appropriate to correlate this strength parameter with the field Strength parameter. Standard penetration test is one of the popular methods used in the field for measurement of strength and is often

Interface Shear Strength at Joints of Ultra

The test results were also compared with two representative predictive equations for interface shear strength to determine an appropriate equation for the joint design of UHPC. These equations did not match well with the test data because they were originally proposed for normal strength concrete.

Iodine test for Starch

Before you perform the Iodine test for starch, here is a list of precautions that you need to take care of before and while performing. Make sure that amount you're taking of samples and liquid drops are the same as mentioned in the procedure. Also, make sure that the test tube you are using must be cleaned and washed very neatly.

The Strength of the Weak Form

29-4-2014The boundary terms require special treatment, which is beyond the scope of this blog post. No equals sign needs to be included, since the weak form PDE is automatically set to zero. It is important to note that this translation is normally done automatically because COMSOL Multiphysics needs the weak form to proceed with the calculation.

The ratio of prediction-to-test for some of these tests is too large to be acceptable. Specifically, consider a mock-up test of a window or curtain wall that uses 150% of the design pressure. Assume that the screws have an allowable pull-out strength, using the A-T method that equals the required pull-out force.

Understanding t

4-5-2016The 2-sample t-test takes your sample data from two groups and boils it down to the t-value. The process is very similar to the 1-sample t-test, and you can still use the analogy of the signal-to-noise ratio. Unlike the paired t-test, the 2-sample t-test requires independent groups for each sample. The formula is below, and then some discussion.
