The department of Mathematics and Statistics invites you to a seminar by
Prof. Mark Ainsworth (Department of Mathematics and Statistics,
University of Strathclyde, UK): 



Title:  Multiscale Modelling and Limit Load Analysis of Masonry

Abstract:  The construction of mathematical models for masonry
structures has attracted considerable attention in both the engineering
and mathematical communities, and a very wide range of models have been
proposed. We choose a very simple model whereby masonry structures are
treated a large number of elastic bodies (bricks or stone-blocks) in
unilateral, frictional contact. The challenge then becomes one of
managing the complexity arising from the large number of individual
units. We present a multiscale approach and show that our very simple
model is capable of reproducing the observed behaviour of some simple
real-life masonry structures. We then turn our attention to the problem
of determining the largest (limit) load that a given structure can
sustain. Again, this so-called limit load analysis problem has been the
subject of considerable attention. We present a new approach whereby
rigorous two-sided bounds on the limit load can be obtained by making
use of recent developments in the theory of mixed finite elements in a
non-standard fashion. 


The seminar will take place on Friday 26th February, at 4pm, in A2-002.
