Supplement to: Sandbox Rheometry: Co-Evolution of Stress and Strain in Riedel- and Critical Wedge-Experiments

This dataset is supplementary to the article of Ritter et al. (2017). In this article, a new experimental device is presented that facilitates precise measurements of boundary forces and surface deformation at high temporal and spatial resolution. This supplementary dataset contains the measurement data from two experiments carried out in this new experimental device: one experiment of an accretionary critical wedge and one of Riedel-type strike-slip deformation. For a detailed description of the set-up and an analysis of the data, please see Ritter et al. (2017). The data available for either experiment are:• A video showing deformation in top view together with the evolution of boundary force. This file is in AVI-format.• A time-series of 2D vector fields describing the surface deformation. These vector fields were obtained from top-view video images of the respective experiment by means of digital image correlation (DIC). Each vector field is contained in a separate file; the files are consecutively numbered. The vector fields are stored in *.mat-files that can be opened using e.g. the software Matlab or the freely available GNU Octave. They take the form of Matlab structure arrays and are compatible to the PIVmat-toolbox by Moisy (2016) that is freely available. The most important fields of the structure are: x and y, that are vectors spanning a coordinate system, and vx and vy, which are arrays containing the actual vector components in x- and y-direction, respectively.• A file containing the measurements of the boundary force applied to drive deformation. This file is also a *.mat-file, containing a structure F with fields force, velocity and position. These fields are vectors describing the force applied by the indenter, the indenter velocity and the indenter position

本数据集为Ritter等人（2017）发表论文的配套补充数据集。该论文提出了一种新型实验装置，可实现高时空分辨率下边界力与表面形变的精准测量。本补充数据集包含该新型实验装置开展的两组实验的测量数据：一组为增生临界楔体（accretionary critical wedge）实验，另一组为Riedel型走滑形变（Riedel-type strike-slip deformation）实验。关于实验装置的详细说明与数据的分析过程，请参阅Ritter等人（2017）的原文。

两组实验均可获取以下数据：
• 一段同时展示顶视形变过程与边界力演化的视频，文件格式为AVI。
• 表征表面形变的二维矢量场时间序列：此类矢量场通过对应实验的顶视视频图像，经数字图像相关（Digital Image Correlation, DIC）技术处理得到。每个矢量场均存储于独立的*.mat格式文件中，文件按顺序编号。此类文件可通过Matlab或开源软件GNU Octave打开，其数据格式为Matlab结构数组，兼容Moisy（2016）发布的开源PIVmat工具箱（PIVmat-toolbox）。该结构数组的核心字段包括：x与y（构成坐标系的矢量数组），以及vx与vy（分别存储x、y方向矢量分量的数组）。
• 包含驱动形变的边界力测量数据的文件，同样为*.mat格式文件，其中包含结构数组F，其字段包括force、velocity与position，分别为表征压头施加的载荷、压头运动速度与压头位置的矢量数组。
