Constitutive modeling of a graded porous polymer based on X-ray computed tomography
Vestrum, Ole; Dæhli, Lars Edvard Blystad; Hopperstad, Odd Sture; Børvik, Tore (Peer reviewed; Journal article, 2020)This work focuses on the constitutive modeling of a graded porous polymer pipeline coating based on X-ray micro computed tomography (XRMCT). Previous work has revealed that finite element (FE) models generated from XRMCT ... -
Ductile failure predictions using micromechanically-based computational models
Dæhli, Lars Edvard Blystad; Tekoglu, Cihan; Morin, David; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2022)Three different micromechanically-based computational models for fracture in porous ductile solids are compared and assessed. Model A is a unit cell model of a porous ductile solid comprising a uniform periodic distribution ... -
Effective behaviour of porous ductile solids with a non-quadratic isotropic matrix yield surface
Dæhli, Lars Edvard Blystad; Hopperstad, Odd Sture; Benallal, Ahmed (Journal article; Peer reviewed, 2019)In this study, we examine the macroscopic yielding of isotropic porous ductile solids having a matrix yield function dependent on the second and third deviatoric stress invariants. Numerical limit analyses using a ... -
Influence of constituent particles on fracture of aluminum alloys under high-triaxiality loading
Dæhli, Lars Edvard Blystad; Olufsen, Sindre Nordmark; Kristensen, Tore Andre; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2023)Single-edge notch bending tests are conducted to study the influence of constituent particles on the fracture resistance of aluminum alloys 6061, 6063, and 6110 under high-constraint loading conditions. The alloys are ... -
Modelling and Simulation of Yielding, Work-Hardening and Fracture of Advanced High-Strength Steels
Lima, Jostein; Aune, Sigurd (Master thesis, 2020)I denne avhandlingen ble eksperiment med syklisk last utført ved bruk av et anti-knekkingsutstyr for å undersøke hvilken påvirkning volumfraksjonen av martensitt har på Bauschingereffekten i tofasestål. Fire forskjellige ... -

A Numerical Study on Ductile Failure of Porous Ductile Solids With Rate-Dependent Matrix Behavior
Dæhli, Lars Edvard Blystad; Morin, David; Børvik, Tore; Benallal, Ahmed; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2020)This work examines the effects of loading rate on the plastic flow and ductile failure of porous solids exhibiting rate-dependent behavior relevant to many structural metals. Two different modeling approaches for ductile ... -
Performance of perforated aluminium plates subjected to blast loading
Sørbøl, Jørgen (Master thesis, 2020)Hovedmålet med denne oppgave er å undersøke oppførselen til tynne deformerbare aluminiumsplater, med og uten perforerte hull, utsatt for eksplosjonslast. Arbeidet består av en omfattende eksperimentell undersøkelse av ...
