This is what you need to know when calculating rubber
Rubber is a devil's work for numerical calculation using numerical simulation. It is not enough to fit a material model on the basis of a tensile test, but you have to know what can happen with rubber in order to be able to make usable statements.
Most calculation engineers usually do not have the time to deal intensively with the material rubber and apply the material laws available in the software packages, to put it mildly, somewhat naively.
Software developers lack the external compulsion to deal with this topic more intensively, since there is only a small circle of potential customers who deal with this topic intensively. If you want to achieve better results here, you have to rely on programming your own subroutines.
Measurement laboratories measure stress-strain curves, friction factors and temperature influences without a deeper understanding of what makes sense here and what may be determined by theoretical approaches on their own.
In short, once again often only colorful pictures are produced, the significance of which is extremely doubtful.
This can result in serious damage if, for example, a seal of a pump in a car fails and has to be replaced.
We want to counteract this with this e-book to make the world of rubber calculation a little simpler and clearer.
