 ultiscale modelling\, analysis and simulation of plant biomechanics and gr
 owth</a>\nby Mariya Ptashnyk (Heriot-Watt University Edinburgh) as part of
  Nečas Seminar on Continuum Mechanics\n\nLecture held in Room K3\,  Facul
 ty of Mathematics and Physics\, Charles University\, Sokolovská 83  Pragu
 e 8..\n\nAbstract\nThe interplay between the complex microscopic structure
 s and microscopic (cellular) processes enables many biological tissues to 
 combine the ability to resist high pressure and mechanical forces with the
  flexibility required for large expansions and growth. To analyse the inte
 ractions between the mechanics\, microscopic structure\, and the chemistry
  we derive microscopic models for plant biomechanics\, assuming that the e
 lastic/viscoelastic properties of plant cell walls depend on the chemical 
 processes and chemical reactions depend on the mechanical stresses. Multip
 licative decomposition of the deformation gradient into elastic and growth
  parts is used to model the stress or strain-based growth. To analyse and 
 simulate the complex multiscale models\, the macroscopic effective equatio
 ns are derived using homogenization techniques. Numerical solutions for th
 e macroscopic models demonstrate the impact of the microscopic structure a
 nd tissue heterogeneity on deformation and growth.\n
