“…It housed a ceramic furnace heater, allowing for heating rates up to 70 °C/min with final temperatures of at least 840 °C uniformly distributed across the sample (see Figure ). Accordingly, the cell was fully capable of Fischer assay type investigations that require a heating rate of 12 °C/min with final temperatures of about 500 °C. − In its current configuration, the cell body was rated for 800 psi (5.6 MPa) for a cell wall temperature of 460 °C as per ASME Section VIII …”

This paper summarizes results of a successful laboratory investigation to visualize and quantify pyrolysis-induced porosity evolution of Uinta Basin organic-rich source rock using X-ray computed tomography (CT). Combining CT imaging techniques with a radio-opaque gas as a pore contrast fluid allowed for the description of porosity changes within source rock rather than limiting quantification to a single bulk value, as obtained by conventional porosity measurement techniques. The porosity of the immature and thermally matured rock sample, a Green River oil shale, increased from 9 to 25% as a result of kerogen conversion and delamination. Porosity distributions of immature samples showed unimodal behavior, whereas matured samples displayed multimodal characteristics. These new measurements indicate that porosity evolution during maturation is not well-described by bulk measurements.

“…It is incumbent on the engineer to do more than carry out the rote execution of a design code. The formal education typical of modern engineers gives them the foundation for the specific design theory, but applying these building blocks requires additional study, such as sources from the code proponent like ASME 6,10,11 or independent engineering texts 12 .…”

Misapplication of Pressure Vessel Codes in Forensic Applications

Engineering codes are a key method to guide designs to safe and reliable outcomes. Many such codes have prescribed calculations where the user provides specific inputs in a series of calculations, often using charts or tables, to get specific outputs. The design margins, units, and underlying theory are not always apparent. Engineering codes may not be suitable for reverse engineering an incident or providing a failure prediction. This article examines a criminal negligence case in which an initial forensic analysis incorrectly applied the ASME Pressure Vessel Code to use Finite Element Analysis (FEA) of a failed pressure vessel section. The flaws in the original analysis were revealed by applying reverse engineering using conventional stress calculations and understanding basic material science. This emphasizes the need to understand the underlying theories with both engineering codes and numerical modeling. Subsequent FEA provided an accurate analysis report that was successfully used in court. These same methods can be applied to many other engineering codes and standards.

“…Because the winding is a long solenoid, the effects of the end plates of mandrel are ignored. Thus, the circumferential stress σ θi in the cylinder composed of i − 1 wound layers and the mandrel under pressure p i can be estimated by the expression [11] σ θi =…”

The applied pretension on the conductor and support condition during coil fabrication has a great effect on the stress state of the coil. Otherwise, the thermal contraction properties of mandrels and coils would cause residual thermal stress during cool down. A combined homogeneous cylinder method was used to analyze the mechanical performance of winding process for the condition of no mandrel support. A finite-element model of solenoid was created to calculate the stress of winding process and cool down. The mandrel support conditions of fixed support at ends of former and radial support along the whole inner surface of former were researched. Mechanical behaviors of one coil used for a 9.4-T magnetic resonance imaging magnet during winding process and cool down were studied based on the aforementioned approach.
