In this paper a new thermo-plastic damage model for plain concrete subjected to
combined thermal and cyclic loading is developed using the concept of plastic-
work-hardening and stiffness degradation in continuum damage mechanics.
damage variables are used, one for mechanical action and the other for thermal
The concrete model is based on the non-associated flow theory of
plasticity with a scalar hardening parameter, a multi-criteria yield function.
Further, thermo-mechanical interaction strains have been introduced to describe
the influence of mechanical loading on the physical process of thermal expansion
The constitutive relations for elastoplastic responses are decoupled
from the degradation damage responses by ...
