A proposed calculation of in situ closure stress allows engineers to select more appropriate proppant. For decades, the calculation for in situ closure stress on proppant has involved subtracting ...
• Shoulder fillets are notches that generate transverse stresses under axial loading. • Von Mises equivalent stresses let engineers determine the maximum principle stress when tension or bending ...
This is a preview. Log in through your library . Abstract The Maxwell-Lamé equations governing the principal components of Cauchy stress for plane deformations are well known in the context of ...
A new study uses shear tests and seepage-stress analysis in north China's Liushagang formation to create a model that predicts collapsing pressure and avoids costly drilling delays in hard, brittle ...
