Simulation of heat and moisture induced stress and strain of historic building materials
Paper in proceedings, 2011
Climate change can cause not only damage, but can
also destroy the basic structure of historic sites, as
well as their associated interior artefacts. The
evaluation of combined heat and moisture induced
stress and strain (HMSS) is a valuable method in
which possible damage-related processes can be
This paper presents the development of one- and
two-dimensional HMSS models of building materials
and artefacts in the commercial finite element
software COMSOL Multiphysics Version 4.1. This
multiphysics software package ensures the
compatibility of modelling combined physical
transports, due to its flexible and adaptable platform.
Validation by means of analytical, numerical and
experimental solutions are also included, along with
numerical simulation results.
The HMSS model was found to be an adequate
predictive tool to determine possible damage-related
processes in building assemblies and artefacts.
