The axiomatic introduction of arbitrary strain tensors by Hans Richter – a commented translation of ‘Strain tensor, strain deviator and stress tensor for finite deformations’

We provide a faithful translation of Hans Richter’s important 1949 paper ‘Verzerrungstensor, Verzerrungsdeviator und Spannungstensor bei endlichen Formänderungen’ from its original German version into English, complemented by an introduction summarizing Richter’s achievements.

Behavior of Cemented Reticulate Red Clay

Mechanical properties of cemented reticulate red clay were studied in present research. Test results show that: (1) shear strength of cemented reticulate red clay increase exponentially as the increasing of cement content; (2) shear strength of cemented reticulate red clay decrease polynomially as the increasing of water content; (3) mechanical properties of cemented reticulate red clay affected significantly by curing time and curing confined pressure. In order to study viscous properties of cemented reticulate red clay, cemented reticulate red clay specimens were compressed in triaxial chamber at different shear rate. Results of the compression tests show that it is obvious that the axial strain-deviator stress relationship of cemented reticulate red clay affects by the strain rate.

Plastic Deformation Behavior of Mild Steel Along Orthogonal Trilinear Strain Trajectories in Three-Dimensional Vector Space of Strain Deviator

An experiment was performed on the plastic deformation of mild steel S15C by applying combined loads to thin-walled tubular specimens so that the deformation developed along orthogonal trilinear strain trajectories in the three-dimensional vector space. Scalar and vectorial history effects on the stress vector σ in the deformation along the third branch are examined for 28 kinds of trajectory combined of various values of an angle θe between the first and third branches and a length sl of the second branch.
