摘要: Abstract Shape fabrics of elliptical objects in rocks are usually assumed to develop by passive behavior inclusions with respect the surrounding material leading shape-based strain analysis methods belonging Rf/ϕ family. A probability density function is derived for orientational characteristics populations rigid ellipses deforming a pure shear 2D deformation both no-slip and slip boundary conditions. Using maximum likelihood numerical method developed estimating finite natural mechanisms. Application example indicates importance mechanism explaining clast shape deformed sediments.
