Nonlinear Creep Model of Paper and Corrugated Board Materials
Models of the nonlinear creep behavior of paper, and of the global buckling , local buckling and creep buckling of corrugated board have been developed. The studies of creep and buckling were limited to climate conditions with constant relative humidity. First the short-term elastic buckling of corrugated board panels was studied. Then an appropriate creep equation, based on the Schapery represent
