Influence of thermal and mechanical stresses on the strength of intact and relined denture bases
(Mosby, Inc, 2006-07-01)
Statement of problem. Denture bases may become increasingly weaker as a result of thermal stress and flexural cyclic loading. Information regarding this potential problem and its relationship to the denture base reline is ...
Influence of crystallinity on interlaminar fracture toughness and impact properties of polyphenylene sulfide/carbon fiber laminates
(2021-01-01)
The crystallization behavior of thermoplastic matrix is considered as an important property which can highly affect for the mechanical and thermal properties of laminated composite structures. This manuscript aims to ...
Supercritical carbonation treatment on extruded fibre-cement reinforced with vegetable fibres
(Elsevier B.V., 2015-02-01)
The objective of this research was to evaluate the effects of supercritical carbonation treatment for 2 h on the main hydrated phases of the cement matrix (calcium hydroxide and calcium silicate hydrate) and durability of ...
Post-depositional fracturing and subsidence of pumice flow deposits: Lascar Volcano, Chile
(Springer, 2012)
Unconsolidated pyroclastic flow deposits of the
1993 eruption of Lascar Volcano, Chile, have, with time,
become increasingly dissected by a network of deeply
penetrating fractures. The fracture network comprises
orthogonal ...
Resistance to fracture of lithium disilicate feldspathic restorations manufactured using a CAD/CAM system and crystallized with different thermal units and programs
(2021)
The aim of this study was to determine the resistance to fracture of feldspathic restorations
with lithium disilicate and crystallized with different ovens and programs. Methods: Sixty monolithic
restorations (LD) (EMAX ...
Effect of thermal cycling on fracture toughness of CAD/CAM materials
(Mosher & Linder, Inc, 2018-08-01)
Purpose: To compare the fracture toughness of four different CAD/CAM materials, (VM) Vitablocs Mark II, (IP) IPS e.max CAD, (LU) LAVA Ultimate, and (VE) Vita Enamic under long thermocycling conditions. Methods: Each type ...

Coupled thermo–mechanical interface model for concrete failure analysis under high temperature
(Elsevier Science Sa, 2015-06)
A thermo–mechanical interface model for failure analysis of concrete subjected to high temperature is presented in this work. The model is an extension of a fracture energy-based interface formulation which now includes ...
