Mismatch Constraint Effect of Creep Crack With Modified Boundary Layer Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mismatch effect plays a crucial role in weldments, and an independent mismatch constraint parameter M* is proposed to characterize the material mismatch constraint effect in this paper. A mismatched modified boundary layer ...
On Creep Fatigue Interaction of Components at Elevated Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The accurate assessment of creep–fatigue interaction is an important issue for industrial components operating with large cyclic thermal and mechanical loads. An extensive review of different aspects of creep fatigue ...
Recent Developments of the Linear Matching Method Framework for Structural Integrity Assessment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear matching method (LMM) subroutines and plug-in tools for structural integrity assessment are now in extensive use in industries for the design and routine assessment of power plant components. This paper presents ...
The Interacting Effect for Collinear Cracks Near Mismatching Bimaterial Interface Under Elastic Creep
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the modified reference stress method is introduced to estimate the C* integral for collinear creep cracks near the mismatching bimaterial interface (MBI) and the process that leads to these solutions is also ...
Limit and Shakedown Analysis of 45-Degree Piping Elbows Under Internal Pressure and In-Plane Bending
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper carries out the limit and shakedown analysis of 45 deg piping elbows made up of elastic–perfectly plastic materials by means of the recently proposed stress compensation method (SCM). The elbows are subjected ...
Modification and Extension of Screening Criteria for Fatigue Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ASME Code VIII-2-2019 and previous versions provided three screening criteria for fatigue analysis. From edition 2004 to 2019, the design factor for material allowable stress decreased and the considered range of permissible ...
A Noncyclic Method for Determination of Accumulated Strain in Stainless Steel 304 Pressure Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results of uniaxial ratcheting tests for stainless steel 304 (SS304) under stresscontrolled condition at room temperature showed that the elastic domain defined in this paper expands with accumulation of plastic ...
Analysis and Inversion of Contact Stress for the Finite Thickness Neo-Hookean Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the theoretical analysis and the inversion of the contact stress on the finite thickness rubber contact surface with the friction effect are investigated. First, an explicit expression of deformation and ...
