Material properties obtained from characterization tests on a representative cured-in-place pipe material have been incorporated into a finite element model which employs a special “composite” beam element. The creep buckling behavior of constrained pipe liners are discussed, and a model correlating the critical time and the applied pressure is proposed. The influence of liner/host pipe geometric parameters on liner buckling is also investigated. The agreement of finite element predictions with physical test data shows the utility of the proposed model.
