In engineering applications elastomers are frequently exposed to complex combinations of mechanical loads (monotonic, static, intermittent and cyclic loads). A better understanding of the material resistance against crack initiation and propagation becomes of increasing practical importance. Real elastomer parts and components are loaded over a very wide range of loading frequency (1 to 10
5
Hz) [
1
]. It is also a well known phenomenon that viscoelastic materials may reveal a hysteretic type heating during cyclic loading [

]. Furthermore, this temperature increase is influenced by various factors, i.e., loading frequency, amplitude, the viscoelastic loss and the heat capacity and conductivity of the elastomer type [

and
4
].
