Material Testing Systems

The Comprehensive Materials Testing System includes everything needed to investigate compression and tensile testing, column buckling, three and four-point bending, shear testing, and stress lines with photoelasticity. In addition to everything the Materials Testing Machine provides, the Comprehensive System includes a sturdy, plastic base with convenient storage for all components and accessories.

Both a Three-Point and Four-Point Bend test can be performed by this apparatus. As a downward force (F) is applied in the middle of the rod/beam, the flex (Δx) is recorded. The ratio (F/Δx) is the effective stiffness of the length of rod/beam being tested. The ratio (F/Δx) is the effective stiffness of the length being tested, and is measured directly from the slope of the F vs. Δx graph.

Measure force and displacement for various materials as they are stretched, compressed, sheared, or bent. Investigate material properties including Young’s Modulus, Tensile Strength, Yield Strength, Ductility and Modulus of Resilience. The Materials Testing Machine measures force with a 7100 N load cell and displacement with an optical encoder. 

In part one, 3 different length plastic I-beams are tested under compression to investigate their method of failure. The way in which a member fails (buckling or not) is determined by its Slenderness Ratio, and is calculated for each beam. 

In part two, the critical force is predicted using the Euler Column Equation. When a compressive force is applied to a long straight column, it will elastically compress until a critical force is reached, where the column will suddenly buckle. 

The PASCO Materials Testing System includes everything needed to do tensile testing straight out of the box. The Materials Testing Machine connects to a computer’s USB port using the included PASCO Airlink interface. The Materials Testing Machine measures force with a 7100 N load cell and displacement using an optical encoder. The software uses automatic variable oversampling to control the sampling rate in order to achieve extreme precision.  

The 3 metal tensile samples are made from 1018 Steel, 360 Brass and 2024-T3 Aluminum. The properties measured for these samples include Young’s Modulus, Yield Strength, Tensile Strength, Ductility, and Modulus of Toughness.
