CRTIME t1 ...tn: are the element ages t (n $\leq$ 25 )for which the function values are specified.
CRTEMP te1 ...tem: are the temperatures T (m $\leq$ 10 )for which functions are specified. If no temperatures are specified then DIANA assumes that the creep function is temperature independent.
Either creep or relaxation functions must be specified with one of the following data records.
CREEPF: specifies discrete creep function(s), jnm is the function value J at element age tn and temperature tem. CREEPF can be used in conjunction with both KELVIN and MAXWEL.
RELAXF: specifies discrete relaxation function(s), enm is the function value E at element age tn and temperature tem. RELAXF can only be used in conjunction with MAXWEL.
