Effect of eccentric moments on seismic ratcheting of single-degree-of-freedom structures [PDF]

open access: yes, 2017
This study describes the background and provides validation of new provisions included in the 2016 amendment to NZS1170.5 to address ratcheting due to the presence of static eccentric moments.

Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Crack Process Investigation in Gears Under Single Tooth Bending Fatigue Condition Using Infrared Thermography and 3D XFEM Numerical Models

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

Experimental Study on the Fatigue Behavior of Ti‐6Al‐4 V Bolted Joints Containing Burrs

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT One‐way assembly accelerates aerospace manufacturing operations but risks leaving drilling burrs within mechanical joints. The detrimental impact of burrs on fatigue strength is widely recognized in the literature, but the mechanisms driving this “knock‐down” remain unclear. This investigation focused on mechanically fastened Ti‐6Al‐4 V single‐

Feedback and Contagion through Distressed Competition

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT Firms tend to compete more aggressively when facing financial distress. This intensified competition reduces profit margins, pushing them further into distress and adversely affecting their industry peers. To study such feedback and contagion effects, we incorporate strategic competition in a dynamic model with long‐term defaultable debt ...

An Assessment of Kinematic Hardening Thermal Ratcheting

open access: yes, 1974
Analytical comparisons are made between the thermal ratcheting response of a kinematic hardening material, a perfectly plastic, and an isotropic hardening material for a two-element assembly.

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Effects of scanner type and prosthesis design–luting protocol combinations on the passive fit of interim implant‐supported complete‐arch fixed dental prostheses

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the effects of scanner type and prosthesis design–luting protocol combinations on the passive fit of interim implant‐supported complete‐arch fixed dental prostheses (ISCFDPs) fabricated using a non‐calibrated splinting grammetry system (OptiSplint).
