CMT STANDARDS FOR CONCRETE AND TENSILE STRENGTH (GROUP 2 AND 5)

• - The ability of a material to withstand a pulling force.

• - Measured in units of force per cross-sectional area.

• TENSILE STRENGTH

• COMPRESSION STRENGTH

• DEFORMATION STRENGTH

These tests determine the mechanical properties of steel and other alloys and ensure materials conform to specified standards for structural applications.

• ASTM A370 STANDARD TEST

• UTM STANDARD TEST

• EXTENSOMETER

It is a point on the curve up to which the value of stress and strain remains proportional.

• Proportional Limit

• Elastic Limit

• Yield Strength

• Breaking Strength

The maximum stress a material can withstand and still return to its original shape after the load is removed.

• Elastic Limit

• Proportional Limit

• Ultimate Tensile Strength

• Breaking Strength

• - The stress a material can withstand without permanent deformation.

• - The stress value that the steel can take while still showing elastic behavior.

• Ultimate Tensile Strength

• Yield Strength

• Breaking Strength

• Elastic Limit

The maximum strength a material can withstand while being stretched or pulled before failing or breaking.

• Ultimate Tensile Strength

• Yield Strength

• Proportional Limit

• Breaking Strength

• - Also known as the Fracture Strength.

• - The maximum amount of tensile stress that the material can withstand before failure.

• Yield Strength

• Breaking Strength

• Elastic Limit

• Proportional Limit

Is used to test the tensile stress and compressive strength of materials.

• Universal Testing Machine (UTM)

• Extensometer

• Shimming Materials

• Steel Bars

An instrument that measures the elongation of a material under stress.

• Extensometer

• Universal Testing Machine (UTM)

• Shimming Materials

• Steel Bars

It tests the deformation by directly placing a physical object onto the sample such as a knife-edge.

• CONTACT EXTENSOMETER

• NON-CONTACT EXTENSOMETER
