Last of my mini post-frenzy on discrete element modelling of slope stability at the kind of decimetric scale... just a quick example I bashed up today with 3 (!) changed lines of code - a seemingly stable slope (top-left) but which contains a lower-dipping weak interface/fracture .. which is limited in extent - this can be seen by the incremental max. shear strain (top right) at this very early, almost non-visible stage of deformation. Middle panel is when things really "kick off", again incr. max shear strain shown on right. Bottom panel is a more evolved stage, with on the right shown the total displacement magnitude... the resolution here is about 1.4 m, frictional-cohesive materials, scale is shown. Enjoy!

TIPS for Dips How do you measure the true dip angle of a sloping reflector in a GPR cross-section? It is not as simple as you might expect but is ultimately pretty easy to calculate. In this TIPS article, we show you how and explain the pitfalls. Read more: https://lnkd.in/gJw8VRVK

The definition of surface integral relies on splitting the surface Σ into small surface elements. Each element is associated with a vector dA of magnitude equal to the area of the element and with direction normal to the element and pointing "outward" (with respect to the orientation of the surface).

Essentially, the local curvature of the manifold is a measure of how the connection varies from point to point. https://lnkd.in/gmmW_NSf

When conducting seismic design and assessment, selecting ground motion records in accordance with building code requirements is crucial for nonlinear time-history verification analysis. But how can you efficiently obtain these records? With Djura’s Record Selector, you can achieve this in just a few clicks, seamlessly adhering to global building codes like Eurocode 8 (including the latest updates), ASCE 7-22, and the Italian building code. Additionally, you can retrieve and utilize the uniform hazard spectra data from the 2013 and 2020 European Seismic Hazard Model (operated by EFEHR at www.efehr.org) directly via API—simply by entering the site coordinates! This same feature has been implemented for the USA with the USGS model and also Turkiye’s national model. https://lnkd.in/dJ3e2Cmv Watch the demonstration video below or try out our demo here: https://lnkd.in/d_K7rXZm 🔗 Try the demo here: https://lnkd.in/d_K7rXZm 💻 Want a live demonstration?
