RUPTURE FORCE – the force that is required to produce a major break/rupture in a
sample – can be related to the firmness and brittleness of a product. It
is related to burst force – the force causing a sample to break
suddenly and violently into pieces. Rupture force measurement can be
crucial for such products as medical implants, which may be required to
resemble soft tissue but must remain intact for the duration of their
intended residence. Several other products, such as gel capsules containing vitamins, possess bursting as a desirable property, but must withstand transport and handling before ultimately bursting in the mouth.
