Hydraulic fracturing is frequently used to increase the permeability of rock formations in energy extraction scenarios such as unconventional oil and gas extraction and enhanced geothermal systems(EGSs).The present study addresses uncertainties in the hydraulic fracturing process pertaining to EGSs in crystalline rock such as ***,there is debate in the literature on the mechanisms(*** and/or shear)by which these fractures initiate,propagate,and *** present experiments on Barre granite with pre-cut flaws where the material is loaded to high far-field stresses close to shear failure,and then the fluid pressure in the flaws is increased to move the Mohr’s circle to the left and observe the initiation and propagation of fractures using high-speed imaging and acoustic emissions(AEs).We find that the hydraulic fractures initiate as tensile microcracks at the flaw tips,and then propagate as a combination of tensile and shear *** focal mechanisms also show elevated levels of tensional microfracturing near the flaw tips during pressurization and final *** then consider a numerical model of the experimental setup,where we find that fractures are indeed likely to initiate at flaw tips in tension even at relatively high far-field stresses of 40 MPa where shear failure is generally expected.

在数值科学和应用科学中,人们经常需要考虑多种类型的序列:标量、向量、四元数、矩阵以及后来出现的张量.这些序列可能收敛,也可能发散.当它们收敛时,其收敛速度可能会非常缓慢,以至于其实际用途十分有限.在某些情况下,可以修改建立这些序列的过程,但在其他情况下,这个过程是一个无法进入的黑箱.那么,规避这一困难的一个可行方法就是将序列变换成另一个序列,希望它能收敛到相同的极限,并且收敛得更快.这种序列变换背后的思想就是外推法.本文是关于这些方法中最重要的方法以及其理论基础和算法方面的导引.本文还介绍了一些应用.
