Dent damage identification in stiffened cylindrical structures using inverse Finite Element Method [PDF]

open access: yesOcean Engineering, 2020
The offshore industry has been using stiffened thin-walled steel cylindrical structures for decades, particularly as the columns of floating offshore installations. The floating offshore installations may be subjected to severe marine environmental conditions. Accidents such as collisions may also occur.

Profilometry‐Based Inverse Finite Element Method Indentation Plastometry [PDF]

open access: yesAdvanced Engineering Materials, 2021
This is a review of the current state‐of‐the‐art regarding a particular approach to extraction of the (quasistatic) stress–strain relationship of a metallic sample from an indentation experiment. It is based on the application of a relatively high load (kN range) to the sample via a large spherical indenter (≈1 mm radius), followed by measurement of ...

Extraction of Fracture Toughness Parameters by Ring-Notched Small Punch Specimen Using Cohesive Model

open access: yesShanghai Jiaotong Daxue xuebao, 2021
The fracture toughness of in-service equipment and irradiation materials can be obtained from the ring-notched small punch specimen. The cohesive model was used to describe the ductile fracture behavior and crack propagation process of T91 steel, and the

Estimation of thermophysic properties of a bimaterial by temperature field measurement and finite element model updating

open access: yesMechanics & Industry, 2023
The aim of this study is to identify simultaneously the thermal conductivity tensor and the heat capacity per unit volume of a bimaterial, whose heat conduction obeys Fourier’s law. This approach is validated by numerical simulation.

Discontinuities without discontinuity: The Weakly-enforced Slip Method [PDF]

open access: yes, 2013
Tectonic faults are commonly modelled as Volterra or Somigliana dislocations in an elastic medium. Various solution methods exist for this problem. However, the methods used in practice are often limiting, motivated by reasons of computational efficiency
