A numerical method of visco-elastic stress analysis
International Journal of Mechanical Sciences, 10 (10):
807--827 (1968)Abstract
By representing the visco-elastic behaviour of a material by a number
of Kelvin models connected in series and by keeping a running total
of creep strain for each such model, the difficulty of retaining
the stress history in computer solutions is avoided. A completely
general method of numerical visco-elastic stress analysis with constant
or temperature variable properties is developed.
The method is checked against some known solutions. Examples from
the fields of propellant technology, concrete and rock behaviour
are included.
