Influence of Temperature Dependent Properties on Tunneling Cracks in Multi‐Layer Polymer Thin Films

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Tunneling cracks severely compromise the mechanical integrity of multi‐layer polymer thin films on stiff substrates. Although previous models assume a constant elastic modulus, this study characterizes four candidate thermoset polymers. Their elastic modulus (E$$ E $$), coefficient of thermal expansion (CTE), and glass transition temperature ...

Mechanical and Metallurgical Evaluation of Four Rotary Nickel‐Titanium File Systems: A Multimethod Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim To compare four rotary nickel‐titanium (NiTi) file systems (Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo) using a multimethod approach to evaluate their mechanical and metallurgical properties. Materials and Methods Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo (all size 25/0.06 with an S‐shaped cross‐section; 52 instruments

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

Journal 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.
