    Course Overview

    Stochastic Mechanics of Materials and Structures

    Synopsis

    This course presents an array of methods to study mechanics of spatially random material microstructures involving several scales. The course begins with lectures on random geometry and stochastic processes and fields, including spatial point processes, mathematical morphology, geodesics, ergodicity, and entropy. Subsequent topics include: periodic versus disordered truss- and beam-type lattices, and a construction of corresponding classical and non-classical (Cosserat, non-local, strain-gradient, chiral …) continua; introduction to statistical continuum theories, including thermomechanics of random media; scaling to Representative Volume Element (RVE) in conductivity, linear or finite (thermo)elasticity, elasto-plasticity, permeability, and coupled field phenomena; methods for problems below the RVE (i.e., those lacking the separation of scales) via micromechanically-based stochastic finite elements; tensor random fields, effects of microscale material randomness on waves and wavefronts (e.g. shocks) in linear and non-linear elastic/dissipative media; introduction to stochastic damage mechanics; elements of fractional calculus and fractals.

     

    Key Topics

    • To develop familiarity with a wide array of methods in mechanics of spatially random materials and structures, specifically:
    • Introduction to stochastic geometric models of microstructures
    • Scalar and tensor random fields; fractal and Hurst effects
    • Scale-dependent homogenization of random elastic/inelastic materials
    • Stochastic (micro)mechanics as a basis for stochastic finite elements (SFE)
    • Waves in random media

     

    Who Should Attend
