Static bending analysis of a transversely cracked strip tapered footing on a two-parameter soil using a new beam finite element
Denis Imamović, Matjaž Skrinar, 2024, izvirni znanstveni članek

Opis: In this paper, a new beam Euler–Bernoulli finite element for the transverse static bending analysis of cracked slender strip tapered footings on an elastic two-parameter soil is presented. Standard Hermitian cubic interpolation functions are selected to derive the closed-form expressions of complete stiffness matrix and the load vector. The efficiency of the proposed finite element is verified on an example with several width tapering variations of a simple cracked footing with the results of governing differential equation. Another novelty of this study is improved bending moment functions with included discontinuity conditions at the crack location. These functions now accurately describe the bending moments in the vicinity of the crack of the finite element.

New linear spring stiffness definition for displacement analysis of cracked beam elements
Matjaž Skrinar, Tomaž Pliberšek, 2004, drugi znanstveni članki

Opis: The paper describes the reasons for the derivation of a new definition of a rotational spring that can be utilised in the simplified computational model for the computation of transverse displacements of cracked beam structures dueto transverse load. This definition plays an extremely important role in the inverse identification of cracks.
