XFEM allows modeling of cracks independently of the mesh and simulation of crack initiation and propagation along arbitrary paths without remeshing. It uses enriched degrees of freedom and level set methods to describe cracks. There are two main approaches to modeling propagating cracks in XFEM: (1) the cohesive segments approach which uses traction-separation laws along phantom nodes across crack surfaces, and (2) the LEFM approach which uses virtual crack closure technique. Both approaches assume no near-tip singularity and require cracks to propagate in entire elements. The document provides details on modeling stationary cracks, using contour integrals, and implementing the cohesive segments and LEFM approaches in Abaqus.Finite Element analysis -Plate ,shell skew plate

Experiment NO:6 describes a compression test performed on an anisotropic wooden material to determine its compressive strength when force is applied both parallel and perpendicular to its fibers. When force was applied perpendicular to the fibers, the wooden block failed at a compressive strength of 4.7712x107 N/m2. When applied parallel to the fibers, the failure strength was lower at 1.204x107 N/m2.

Scrum is not #perfectMateusz 纏eromski

Scrum is not always the perfect framework for software development in every situation. While Scrum allows for high impact and value early on when first developing an MVP, adding additional value and features becomes more complicated over time. Additionally, at the early startup stage Scrum ceremonies can be too complex and slow down the need for fast iteration. Later, when a product has many features, extending it requires more effort and Scrum ceremonies like daily standups may become less useful. It is suggested to switch to a Kanban approach without timeboxed sprints in these situations. The key is to start without strict processes, introduce Scrum rules when problems occur, and be willing to transition frameworks as the needs of the team change over time.In the Scrum the PO role is a key
