Modulus Of Rupture Furnaces

Vecstar’s Hot Modulus of rupture Furnaces are designed and manufactured to customer specifications. Model shown has a lloyd material testing unit. Vecstar’s modulus of rupture furnaces are designed with a maximum temperature up to 1700°C.Independent over-temperature protection is available as an option, using a digital alarm working from a separate thermocouple, safeguarding both the furnace or any furnace contents from over-heat damage at any temperature.


Our modulus of rupture furnaces are supported by a wide range of equipment and extras such as RS 232, RS 485 comms, digital controllers, programmers, recorders and furnace tables.


We design and build in house so if you have a bespoke requirement please do not hesitate to contact us.Our in-house experts and CAD design team are on hand to assist you and will complete your project through consultancy, design, manufacture, installation and ongoing support.


Full training and ongoing support is offered as standard and we promise the best possible service.

Available in the UK, USA and Worldwide directly through Vecstar or through our approved distributors.



Flexural strength, also known as modulus of rupture, bend strength, or fracture strength, is a material property, defined as the stress in a material just before it yields in a flexure test. The transverse bending test is most frequently employed, in which a specimen having either a circular or rectangular cross-section is bent until fracture or yielding using a three point flexural technique. The flexural strength represents the highest stress experienced within the material at its moment of rupture. It is measured in terms of stress.

When an object formed of a single material, like a wooden beam or a steel rod, is bent, it experiences a range of stresses across its depth. At the edge of the object on the inside of the bend (concave face) the stress will be at its maximum compressive stress value. At the outside of the bend (convex face) the stress will be at its maximum tensile value. These inner and outer edges of the beam or rod are known as the ‘extreme fibers’. Most materials fail under tensile stress before they fail under compressive stress, so the maximum tensile stress value that can be sustained before the beam or rod fails is its flexural strength.
