Characterization Of Damage In A Limestone
Author(s)
K. De Proft & W.P. De Wilde
Abstract
An experimental test setup for mode I fracture in limestone (stone of Massangis)
is used for the determination of the parameters of a strain softening material
model. Double edge notched rectangular specimens are tested in tension. Both
global, i.e. load displacement curve, and local, i.e. crack path, behavior are
studied during the tests. Difficulties arising in the experimental measurement of
strain softening behavior in traction will be discussed. Experimental results are
used as input for a finite element model. Material parameters are updated until a
matching response is found.
1 Introduction
Nowadays, historical buildings are often renovated and reused. However, the
loading conditions in the new situation may differ significantly from the initial
loading taken into consideration during the initia
