Title: DEVELOPMENT OF A RHEOLOGICAL MODEL FOR CREEP STRAIN EVOLUTION IN STEEL AND ALUMINIUM AT HIGH TEMPERATURE
Source: Fire and materials (0308-0501) (2018)
Paper status: accepted
Keywords: Rheological model, Creep properties, Steel, Aluminium, High temperature, Fire
Abstract:
The paper presents a rheological model capable of reproducing the temperature-, stress- and time- dependent strain component which occurs in steel and aluminium during exposure to high temperature. The model is capable of providing the creep strain output for the primary, secondary and tertiary creep phases for both steel and aluminium. Constitutive parameters of the rheological model are calibrated using two recent coupon test studies based on the European steel grade S275JR and aluminium grade EN6082AW T6, both of which are currently used in the construction industry. The calibrated constitutive parameters are valid within the temperature range within which creep is expected to occur (400-600°C for steel and 200- 300°C for aluminium). The rheological model proposed in the paper can easily be used for application in finite-element-based computer codes.
