3D numerical modelling of twisting cracks under bending and torsion of skew notched beams
Benedetti, Lorenzo; Cervera Ruiz, Miguel; Chiumenti, Michele (2017-05)
Article
Accés obertThe testing of mode III and mixed mode failure is every so often encountered in the dedicated literature of mechanical characterization of brittle and quasi-brittle materials. In this work, the application of the mixed ... -
High-fidelity prediction of crack formation in 2D and 3D pullout tests
Benedetti, Lorenzo; Cervera Ruiz, Miguel; Chiumenti, Michele (2016-08)
Article
Accés obertThis paper presents the 2D and 3D numerical analysis of pullout tests on steel anchorages in concrete blocks using standard and mixed finite elements. A novel (stabilized) mixed formulation in the variables of total strain ... -
Mixed finite element formulations for strain localization and failure in plasticity
Benedetti, Lorenzo (Universitat Politècnica de Catalunya, 2017-05-11)
Tesi
Accés obertStrain localization and quasi-brittle failure in frictional-cohesive materials is still an open and challenging problem in computational mechanics. Owing to its complexity and the significant implications on numerous ... -
Mixed stabilized finite element methods in nonlinear solid mechanics. Part III: compressible and incompressible plasticity
Cervera Ruiz, Miguel; Chiumenti, Michele; Benedetti, Lorenzo; Codina, Ramon (2015-03)
Article
Accés obertThis paper presents the application of a stabilized mixed strain/displacement finite element formulation for the solution of nonlinear solid mechanics problems involving compressible and incompressible plasticity. The ... -
Stress-accurate Mixed FEM for soil failure under shallow foundations involving strain localization in plasticity
Benedetti, Lorenzo; Cervera Ruiz, Miguel; Chiumenti, Michele (2015-03)
Article
Accés obertThe development of slip lines, due to strain localization, is a common cause for failure of soil in many circumstances investigated in geotechnical engineering. Through the use of numerical methods - like finite elements ...
