Universal Testing Machine
A universal testing machine (UTM), also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials. An earlier name for a tensile testing machine is a tensometer.
​
The "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and structures (in other words, that it is versatile).
Oedometer / Consolidation Tests
An oedometer test is a kind of geotechnical investigation performed in geotechnical engineering that measures a soil's consolidation properties.
​
Oedometer tests are performed by applying different loads to a soil sample and measuring the deformation response.
​
The results from these tests are used to predict how a soil in the field will deform in response to a change in effective stress.
Unconfined Compressive Strength Tests
The unconfined compression test stands out as a widely employed technique for assessing soil shear strength due to its expeditious and cost-effective nature. Primarily utilized for saturated, cohesive soils extracted from thin-walled sampling tubes, this method proves less applicable to cohesionless or coarse-grained soils.
​
Operating on a strain-controlled basis, the test becomes particularly relevant in scenarios where soil samples are loaded rapidly, causing rapid changes in pore pressures (water within the soil). This phenomenon is representative of construction sites characterized by swift construction rates, where pore waters lack sufficient time to dissipate.
Triaxial and Permeability Tests
A triaxial test is performed on a cylindrical core soil or rock sample to determine its shear strength while a permeability test is the measure of the flow of a liquid through a soil sample. A soil consists of solid particles with void spaces in between.
​
Generally, a granular material (sands and gavels) has larger void spaces allowing higher flow, and a fine-grained soil (silts and clays) has smaller voids, limiting flow.
