Sousamli, M. (author)There is a very popular fable, dating back to the early 1800s, about three little pigs that build their houses of different materials and a wolf that tries to catch them by blowing down their houses. From the three houses built from straws, sticks or bricks, only the house made out of bricks withstands the blow of the wolf. Although the moral of...doctoral thesis 2024

Poinelli, M. (author)Ice, a pervasive element across the Solar System, holds immense importance in understanding the response of the Earth to ongoing climate change as well as the dynamics of planetary bodies. This dissertation investigates ice fractures on terrestrial and planetary ice bodies, focusing on their impact on the melting of ice shelves in Antarctica and...doctoral thesis 2023

Unnikrishnan, Gokul Krishna (author), Sharma, S. (author), Pathak, Himanshu (author), Chauhan, Vishal Singh (author), Jain, Satish Chandra (author)To accurately analyze the fracture behavior of piezoceramics at small length scales, flexoelectricity must be considered along with piezoelectricity. Due to its dependence on size, flexoelectricity predominates at the micro- and nano-length scales. Additionally, crack tips having the largest strain gradient state cause large flexoelectricity...journal article 2023

Pavlovic, M. (author), Christoforidou, A. (author), Keller, Thomas (author)Challenges of reliable prediction of resistance of bonded joints lie in the complexity of stress concentrations, multiple crack paths, mode-mixity and sudden crack propagation. The new Technical Specification for Design of fibre-polymer composite structures (TS) is bridging this gap by providing comprehensive sets of design recommendations and...conference paper 2022

Mororó, L. A. T. (author), van der Meer, F.P. (author)The thick level set (TLS) method has been proposed as a nonlocal damage model for the modeling of failure in solids being able to deal with crack initiation, branching, and merging. The nonlocality of the TLS is achieved by introducing a characteristic length into the problem. This way, the TLS does not suffer from spurious localization in the...journal article 2021

Alderliesten, R.C. (author)With the introduction of fibre metal laminates (FMLs) as a (fatigue) damage tolerant material concept in aeronautics, an interesting field emerged where fatigue damage interaction plays a dominant role. The hybrid concept effectively demands evaluating fatigue damage growth based on fracture phenomena typical for both metals and fibre...journal article 2019

Lottman, B.B.G. (author)The spalling damage observed to concrete structures after severe fire exposure has been the topic of scientific research for the past decades. This phenomenon is commonly characterised by the sudden and in some cases violent breaking off of concrete pieces from the cross-section. In this thesis the derivation and the numerical results of a...doctoral thesis 2017

Van der Put, T.A.C.M. (author)It is shown that the postulate of strain softening of the fracture stress is based on the error to regard the nominal stress to be the actual, ultimate stress, at the actual area of the fracture plan. Strain sof-tening called yield drop is elastic unloading of the actual elastic stress at the intact, not ltimate, elas-tic loaded part of the...journal article 2015

Sacchetti, F. (author), Grouve, W.J.B. (author), Warnet, L.L. (author), Fernandez Villegas, I. (author)Carbon fibre-reinforced thermoplastic composites laminates (CFRP) meant for fusion bonding have been moulded using different release media. The potential contamination of the laminate surface by the release media and its effect on the mechanical performance of fusion bonded joints was studied. The physical and chemical state of the bonding...conference paper 2015

Pascoe, J.A. (author), Alderliesten, R.C. (author), Benedictus, R. (author)Current prediction methods for growth of disbonds under fatigue loading are generally based on a correlation with either the maximum strain energy release rate (SERR) or the SERR range. This paper highlights some issues with this approach. In particular, it is argued that the maximum SERR or the SERR range alone do not give sufficient...journal article 2014

Van der Put, T.A.C.M. (author)The results of an investigation of splitting of joints of [1] are used for a discussion of design methods and as necessary answer on comments and for confirmation of the extended fracture mechanics theory which accounts for the part of the external energy which is needed for plastic dissipation at the dowels, (which cause the crack opening). It...journal article 2014

Van der Put, T.A.C.M. (author)The exact derivation of the mode I geometric correction factor is given, based on the small crack merging mechanism to show that this always is the real fracture mechanism in wood. This mechanism dominates at late softening and explains fully the apparent decrease of the energy release rate of macrocrack extension as already known for mode I and...journal article 2014

Derelioglu, Z. (author), Ponnusami, S.A. (author), Turteltaub, S. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)Crack healing in ceramic thermal barrier coatings (TBCs) may be realized by embedding Mo-Si based particles in the thermal barrier coating. Upon cracking, these particles are exposed to oxygen that permeates through the top layer and the crack gap is filled with SiO2 which is produced from oxidation at high temperature. Due to its amorphous...conference paper 2013

Wilson, G.S. (author)The excellent durability performance of Glare, a thin fiber metal laminate (FML) material system, is now being proven in service. This has motivated work towards the application of FMLs to thicker structures driven by damage tolerance. In order to fully characterize the crack growth life of such materials, models are necessary that can account...doctoral thesis 2013

Sadeghinia, M. (author)Thin layers of dissimilar materials are used in most microelectronic components in order to achieve special functional requirements. Generally, the interface between two adjacent materials forms a weak link, not only because of the relatively low delamination strength, but also because of the existing mismatch in thermo-mechanical properties,...doctoral thesis 2013

Xiao, A. (author)Due to the fact that microelectronics is made up from various materials with highly dissimilar thermo-mechanical properties, generally the interface between two adjacent materials is the place where delamination related failure most likely would occur. Failure of these interfaces results in decreased reliability and loss of performance of...doctoral thesis 2012

Schlottig, G. (author)This book describes a setup that allows to delaminate the Silicon-to-Molding Compound interface for obtaining interfacial fracture parameters: the Mixed Mode Chisel setup (MMC). With this device for the first time the delamination can be initiated and propagated, while preventing the occurrence of random brittle fracture in one or both of the...doctoral thesis 2012

Hille, T.S. (author)Thermal barrier coatings (TBCs) are applied in gas turbines to enhance their thermal efficiency by isolating the metallic components from the aggressive hot gas. TBC lifetime is limited by damage processes originating at internal interfaces, which may ultimately lead to delamination and spallation. In the present thesis constitutive models are...doctoral thesis 2009
