Damage Propagation at the Interface of a Sandwich Beam

open access: yesPeriodica Polytechnica Civil Engineering, 2022
In this research work, damage propagation at the interface of a cracked sandwich beam is considered. The behavior of Sandwich Beams (SB) depends upon a law based on relationship between tangential or normal efforts with inelastic propagation. As the crack propagates; fracture parameters such as stress intensity factors and energy release rates ...

Low velocity impact modeling in composite laminates capturing permanent indentation [PDF]

open access: yes, 2012
This paper deals with impact damage and permanent indentation modeling. A numerical model has been elaborated in order to simulate the different impact damage types developing during low velocity/low energy impact.

Interface damage model for fatigue-driven fracture [PDF]

open access: yes, 2018
A fatigue interface damage model is presented that is based on combining a fatigue evolution law with a static interface damage model. The fatigue model elegantly enables the simulation of crack initiation and propagation in a computationally efficient ...

Damages and cracks in ceramic/metal interfaces [PDF]

open access: yesLe Journal de Physique IV, 1993
When metal/ceramic junctions are achieved by solid state bonding process, damages and cracks are often observed near by the interface. This paper focuses on the mechanical origin of the embrittlement. The main causes are : - residual stresses due to the mismatch in the mechanical properties of the materials to be joined - friction of metal on the ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Modelling of impact damage and permanent indentation on laminate composite plate [PDF]

open access: yes, 2010
This paper deals with impact damage and permanent indentation modelling. A model enabling the formation of damages developing during a low velocity / low energy impact test on laminate composite panels has been elaborated.
