Structural properties of acrylic
Acrylic is largely used to emphasise some visible appearance where the structural properties
is not essential. But in some designs it is extremely important that the acrylic
can withstand predefined static and dynamic stresses. Eg. catwalks and aquariums.
Construction in acrylic is more complex than steel, because both time and temperature has
influence on acrylic properties (acrylic is visco-elastic, steel is linear elastic-ideal plastic).
This means that the acrylic strength will change depending on how long it has been loaded and
in what temperature. The strength is also reduces when acrylic is exposed to sunlight and especially organic
solvents. Acrylic used in higher security groups must therefore be regularly inspected.
