The STRENGTH of MATERIALS range enables clear and comprehensive learning of Materials and their Properties covering a variety of theories and topics. An understanding of the way in which materials act and react, is fundamental when studying the application of loads on a variety of fixed or moving structures. The STRENGTH of MATERIALS form a comprehensive range of equipment, from fixed beams through to rotating machines apparatus, equally suitable for demonstration and experimental work.

All the STRENGTH of MATERIALS hardware operates in a standalone mode, with a large number being supplied with Data Acquisition Interfaces and Software.



HSM35 Torsion and Deflection Testing Apparatus

This bench top unit allows a variety of experiments to be undertaken to investigate test specimens under torsional loading and bending loading within their elastic limits.

The students cover topics involving bending moment equation, torsional rigidity, modulus of rigidity, angle of twist, and create graphs and compare actual measured values with theoretical values using formulae and theory provided.

HSM38 Polariscope

The HSM38 polariscope is a bench top mounted frame which allows the study of stress patterns and photoelasticity resulting from geometrical changes in loaded mechanical models.

The frame has integral slides into which fit quarter wave plates and polarisation filters. These plates and filters can be rotated through 90° to vary the colourisation seen by the user.

The frame can sit on top of a light box (optional HSM38D) or overhead projector (not supplied). Rubber mounting feet enable it to sit firmly onto the light source.

HSM40 Torsion Testing Machine (200Nm)

A sturdy bench top mounted unit for torsion testing of varying material test specimens to failure/destruction. Using a speed controlled electric motor torque is applied through the drive gearboxes rigidly attached at one end of the base frame.

HSM41 Pendulum Impact Tester (25J)

A sturdy bench top mounted unit for the study of notched bar (Charpy) impact strength tests.

A sturdy base plate with protective guard surround houses all the components, the guard has a lockable door for ease of access when setting the test but also security whist not in use. The base plate has an anvil and pillar which have replicable impact profiles for supporting the notched specimens prior to testing.

HSM45 Transmitted Light Polariscope

The HSM45 polariscope is a bench top mounted frame which allows the study of stress patterns and photoelasticity resulting from geometrical changes in loaded mechanical models.

Photoelastic analysis is achieved by passing light through the mechanical stress models while a tensile load is applied.

The frame has the polarisation filter and quarter wave plate mounted to rotational frames. These frames allow the rotational angle of the plates and filters to be adjusted and hence vary the colourisation seen by the user.
