Double shear test is used to determine the shear strength (ultimate shear stress) of the mild steel specimen. Universal testing machine (UTM) is used for performing double shear test. There are two types of UTM namely: screw type and hydraulic ...

Bulk Density and Void Percentage Test for Aggregates
The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based ...
Variable Head Permeability Test of Soil- Purpose, and Procedures
Variable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow ...
Transverse Strength Test on Roofing Tiles Based on ASTM C 1167 and IS
The transverse strength test of roofing tile is commonly carried out based on the specifications of applicable standards such as ASTM 1167-11 and IS 13801. It involves wet or dry method test and conducted in the lab to estimate breaking ...
Water Absorption Test on Roofing Tiles
Water absorption test is the measurement of moisture quantity that roofing tile may absorb. If water absorption is too high, the tile may suffer from cracking which is not desirable. So, this test reflects the suitability of the tile for ...
Stress-strain Curve for Steel Bars
The stress-strain curve describes the behavior of steel bars under loads. It is created by testing steel specimens. A steel specimen is gradually pulled through a testing machine until it breaks, and stress and corresponding strains are recorded. The stresses ...
Universal Testing Machine – Components and Functions
A Universal testing machine (UTM) is used to test the mechanical properties (tension, compression etc.) of a given test specimen by exerting tensile, compressive or transverse stresses. The machine has been named so because of the wide range of tests ...
Strut Test to Determine Euler’s Buckling Load of Strut
Strut test is used to determine the Euler’s buckling load of the strut. Struts are long, slender columns that fail by buckling some time before the yield stress in compression is reached. The Euler’s buckling load is a critical load ...
