RISAn Equivalent Constitutive Model of Cancellous Bone With Fracture Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To simulate the mechanical and fracture behaviors of cancellous bone in three anatomical directions and to develop an equivalent constitutive model. Microscale extended finite element method (XFEM) models of a cancellous ...
Measurement and Characterization of the Initial Geometric Imperfections in High Strength U ing, O ing and Expanding Manufactured Steel Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The geometric imperfections in high strength Uing, Oing and expanding (UOE) manufactured pipes are investigated in this paper using a highresolution 3D surface scanner, and a reverse engineering and inspection software. ...
Numerical Analysis of API 5 L X42 and X52 Vintage Pipes With Cracks in Corrosion Defects Using Extended Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cracks and corrosion in pipelines can occur simultaneously, representing a hybrid defect known as cracks in corrosion (CIC), which is often difficult to model using the available assessment codes or methods. As a result, ...
Numerical Assessment of Elbow Element Response Under Internal Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a detailed assessment for the response of elbow elements in ABAQUS under internal pressure. Two main cases are considered: (1) a standalone 90 deg pipe bend, which was analyzed using both elastic and ...
Investigation of Fracture Prediction Capability of XFEM and Finite Element Method Using SENT Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the fracture behavior of single-edge notched tension (SENT) specimens made from API X52 vintage pipeline steel by comparing the extended finite element method (XFEM) and the traditional finite element ...
Development of a Tensile Strain Capacity Predictive Model for American Petroleum Institute 5L X42 Welded Vintage Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pipelines can be exposed to a wide variety of loads, depending on the environments and the area of application. These loads may impose large longitudinal plastic strain on pipelines, which could constitute a significant ...
Experimental and Numerical Investigation on Ductile Fracture of Steel Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rupture of steel pipelines leads to the loss-of-containment that may be accompanied with loss of life or damage to property and environment. Therefore, the understanding of the fracture characteristics of steel grades used ...
Variations in the Postbuckling Behavior of Straight Pipes Due to Steel Grade and Internal Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pipelines can be subjected to bending loads due to a variety of factors such as seismic activity, slope instability, or discontinuous permafrost. Experimental studies of Sen et al. [1–3] showed that pipelines can fail under ...
The Effect of Internal Pressure on the Tensile Strain Capacity of X52 Pipelines With Circumferential Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wide plate testing has been traditionally applied to evaluate the tensile strain capacity (TSC) of pipelines with girth weld flaws. These wide plate tests cannot incorporate the effect of internal pressure, however, numerical ...
Effects of the Initial Geometric Imperfections on the Buckling Behavior of High Strength UOE Manufactured Steel Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of the initial geometric imperfections on the buckling response of grade X100 UOE manufactured pipes are studied through finite element analysis (FEA). The initial geometric imperfections had been previously ...
