Constraining stress
WebNov 19, 2024 · Another influencing factor that could promote the residual stress development is the constraining of the plates towards the anvil. This is investigated by considering the longitudinal stress development in the plate during the FSW process. In Figure 7b, the longitudinal stress field from the numerical simulation just before cool … Web10,084 ZAJAC AND STOCK: BREAKOUTS CONSTRAINING STRESS TENSORS determines a regional stress state localized over a spa- tial extent of kilometers to tens of kilometers. Other authors have presented different techniques of using deviated boreholes to determine the local stress state. Qian and Pedersen [1991] applied a nonlinear

WebMay 10, 2016 · Abstract. We constrain the state of tectonic stress in the Nankai accretionary wedge at the Integrated Ocean Drilling Program (IODP) site C0002, southwest Japan, based on borehole wall failures such as breakouts and drilling-induced tensile fractures (DITFs) observed during IODP Expedition 338.

When considering exploration fields with planned wells being drilled to 5500-m TVD, it is imperative to quantify tectonic effects at the well location. In addition, accurately predicting stress profile and …

However, by applying an experimentally derived expression to the strain data that accounts for the constraining stress of overburden pressure, pore pressure, coal type, and gas type; two of the models were …
WebApr 5, 2024 · This model calculates fine, but as can be expected, I have a stress peak at the side of the surface region. Not sure if that is entirely realistic. A slightly different approach is to exchange the screw hole by an 'embedded' bolt, and constrain the tip of the 'bolt': This results in a (lower) stress peak at the indicated spot below.
