Metal-composite joints connecting conventional steel to an advanced fiber composite are an attractive structural system for hybrid ship hulls as well as aircraft frames. The objective of this study is to analyze the size effect on the strength of hybrid joints numerically, theoretically and experimentally. In the numerical analysis, linear elastic continuum elements are used for the composite a...

The purpose of this research was to present a simulation modelling crack propagation trajectory in linear elastic material subjected mixed-mode loadings and investigate the effects existence hole geometrical thickness on fatigue growth life under constant amplitude loading. For various geometry thickness, (I/II) studies were carried out utilize single edge cracked plate with three holes compact...

Large scale laboratory experiments on size and rate effects the fracture of warm columnar freshwater ice have been conducted with floating edge-cracked rectangular plates loaded at crack mouth. The largest test plate had dimensions 19.5m x 36m. overall crack-parallel dimension covered a range 1 : 39 , possibly for tested under conditions. loading rates applied led to durations from fewer than 2...

Fatigue and monotonic test specimens having porosity ranging from microto macroscopic levels were cast from 8630 steel. Monotonic and fatigue properties were obtained to determine the effect of porosity on the mechanical performance of the cast steel. Axial fatigue tests were conducted under fully reversed conditions in both strain and load control on specimens containing microporosity, and in ...

Adhesively bonding has been increasingly used for numerous industrial applications to meet the high demand lightweight and safer structures. Debonding of adhesively bonded joints is a typical mixed mode failure process. It highly depended on interactional effects material properties geometric definitions constituents, which very complicated. The existing studies in identifying fracture modes ba...

Modeling of crack propagation by a finite element method under mixed mode conditions is of prime importance in the fracture mechanics. This article describes an application of finite element method to the analysis of mixed mode crack growth in linear elastic fracture mechanics. Crack - growth process is simulated by an incremental crack-extension analysis based on the maximum principal stress c...

Under low confinement axial compression, the failure of brittle rock is mainly caused by tensile fracture. Many scholars adopt sliding crack as an idealized model to present intrinsic mechanism but due complex configuration crack, its stress intensity factor (SIF) calculation has always been a difficult problem. In this study, improved proposed; in context linear elastic fracture mechanics (LEF...

Welding is a commonly applied joining method in many applications arctic and marine conditions, e.g., ship offshore structures, energy production equipment. Such are usually subjected to fluctuating load during decades-long service, they may experience millions of cycles. Consequently, fatigue strength design acceptable flaw sizes the welded details these structures among most important criteri...

To investigate the fatigue performance of stud connectors steel-concrete structures, crack propagation analysis and life calculation were carried out. Firstly, finite element model with initial based on linear elastic fracture mechanics (LEFM) was established, parameter stress intensity factors (SIFs) studs cracks different geometric sizes performed. Then, mixed-type I-type calculated, variatio...
