摘要：Methods, program products, and computer systems for estimating a stress of a
toughened structural adhesive polymer are provided. One method comprises selecting astrain, a strain rate, a temperature, or a combination thereof at which the stress is to beestimated. A value of a strain-hardening stress of the toughened structural adhesivepolymer is determined, wherein the value of the strain-hardening stress is dependent onthe temperature and the strain. A value of a non-strain-hardening stress of thetoughened structural adhesive polymer is determined, wherein the value of the non-strain-hardening stress is dependent on the strain, the strain rate, and the temperature.The value of the strain-hardening stress is added to the value of the non-strain-hardeningstress to obtain an estimated total stress.
