Design And Analysis Of Four-point Bending Test Rig For Ladder Frame

Journal of Applied Science and Engineering, 2022
This paper describes the design and analysis of a four-point bending test rig for ladder frame specimens. The test rig is used to support the specimen at two equal points when the transverse load is applied.

Test Loading of Structures with a Suspect Resistance

Applied Sciences, 2021
The reliability of load-bearing structures is normally secured through codes, a competent structural design and proper execution inspection. Alternatively, the reliability can be obtained via skilled test loading, which is a feasible technique both in ...

Estimation of modulus of elasticity of compacted loess soil and lateritic-loess soil from laboratory plate bearing test

Case Studies in Construction Materials, 2022
In this paper, the moduli of elasticity of compacted loess and lateritic-loess soils on-site were estimated from the laboratory test. These were coarse grain soils used for the construction of base course and embankment of the railway line. The knowledge

Development of biaxial test fixture includes cryogenic application [PDF]

, 1968
Test fixture has the capability of producing biaxial stress fields in test specimens to the point of failure. It determines biaxial stress by dividing the applied load by the net cross section. With modification it can evaluate materials, design concepts,

Correlation between Uniaxial Compressive Strength and Point Load Strength of Penang Island Granites

IOP Conference Series: Earth and Environment, 2022
Uniaxial compressive strength (UCS) is one of the most widely used strength parameters in geotechnical design. The value is obtained through direct testing method, carried out through careful procedures of testing in a laboratory setting.
