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.

HSM19D Rotating Fatigue Machine (Digital)

This apparatus has been designed to introduce students to the effects of material fatigue. A motor rotates a specimen through a gear and pulley arrangement which can be adjusted. During the rotation the specimen is subject to sinusoidal variation of bending stress. Loads are applied to the test specimen using a screw jack loading mechanism with integral load cell. When failure occurs, a microswitch stops the motor and the cycles to failure are registered on a revolution counter. A safety guard shields all rotating parts. The apparatus is mounted on a heavy base plate. Specially machined necked test specimens are provided.

HSM20 Alternating Bending Fatigue Machine

The HSM20 Alternating Bending Fatigue Machine is a further evolution of the popular HSM19 Rotating fatigue Machine. Rather than rotating a specimen to fatigue failure, the HSM20 induces an alternating displacement to the free end of a cantilevered test specimen in order to fatigue fail the part.

A heavy base plate houses the control box, motor, fluctuating components, test specimen and digital counter. All these parts are enclosed by a transparent safety guard, which ensures rotating components are kept away from the user but full view of parts and count is kept.

HSM30 Unsymmetrical Cantilever Apparatus

This apparatus allows the vertical and horizontal deflections of the free end of a test specimen to be measured when loading occurs along a principle axis or at a known angle.

HSM31 Torsion Testing Machine (30Nm)

A sturdy bench mounted unit for studying applied torque against angle of twist, specimen failure, and test graphs. Torque is applied via the moment head to differing material test specimens using hand operated worm and wheel gearbox.

HSM34 Creep Testing Machine

A sturdy bench top mounted unit for studying the affect of creep on different material test specimens. Necked test specimens are held vertically in position on special clamps, which do not induce bending during loading. A lever arm transmits the load from a load hanger and weights into the specimen and the lever arm has a counter balance weight to ensure the lever arm self weight is calibrated out.
