Surface Strain Measurement for Non-Intrusive Internal Pressure Evaluation of a Cannon
… require testing. This includes measuring the internal pressure during fire. There are concerns with the current method of drilling to mount pressure transducers near the breech and chamber of the gun barrel where pressure is highest. An alternative, non-intrusive strain measurement method is …

Development of internal pressure monitoring system for control of explosive spalling in refractory castables
… cement phases causes build-up of high levels of internal steam pressure. If this pressure exceeds material strength, explosive spalling results. A probe capable of measuring internal steam pressures"in-situ" has been developed and tested. Correlation of cement calorimetry and pressure data …

The Development of a Procedure to Determine the Structural Adequacy Against Buckling of Torispherical and Ellipsoidal Shells Due to Internal Pressure.
Internally pressurized cylinders are used in many industries and they frequently have closed ends of shells of revolution. These closed end shells of revolution are usually torispherical or ellipsoidal shells and they are in common use in fluid cokers in the chemical industry, vessels containing …

Inflated conical membrane subjected to axial compressive load
… would allow taking into account the variation in pressure. This could be done by assuming that the internal pressure P used in the analysis was the pressure after deformation. During deformation, the mass of the enclosed gas remains constant. Thus, knowing the initial and final volumes and the …

A study of the behaviour of pressurized piping elbows
The behaviour of piping elbows under bending and internal pressure is more complicated than expected. The main problem is that the coupling of bending and internal pressure is non-linear; stress and displacement cannot be added according to the principle of superposition. In addition, internal …

Analysis and optimal design of pressurized, imperfect, anisotropic ring-stiffened cylinders
… subjected to axial compression, torsion, and internal pressure is presented. The structure is modeled as a branched shell. A nonlinear axisymmetric prebuckling equilibrium state is assumed which is amenable to exact solution within each branch. Buckling displacements are represented by a …

Avaliação de concentração de tensão em dutos danificados sob pressão interna após reparo
… due to mechanical damage in steel pipes under internal pressure before and after repair. The work is focused on the development of a numerical model, based on the finite element method, to produce stress concentration factors of plain dents before and after applying glass fiber reinforced epoxy …

Internal pressure's role in the selectivity of the bromine radical
… selectivity in free radical brominations and the internal pressure of solvent. The study encompassed l8 solvents and/or mixtures over which the rate constant ratio for SH2 ring opening of cyclopropylbenzene (kC) vs hydrogen abstraction from toluene (kH) by bromine atom was found to vary by nearly …

Thermo-Mechanical Behavior of Polymer Composites Exposed to Fire
… PMCs with a hypodermic needle inserted for internal pressure measurement. One-sided heating tests are conducted on the glass/vinyl ester composites to measure the pressure at different locations through thickness during the decomposition process. The model is employed to simulate the heating …

Characterizing the mechanical properties of drop stitch inflatable structures
… beam bending tests were performed at different pressures. This data was then used to invalidate a developed model for the deflection of the sample. High standard deviations indicate that the pressure inside the tested sample was changing throughout the duration of the tests. An elastic modulus …

Vibration Analysis of Single - Anchor Inflatable Dams
… analysis is performed for different values of internal pressure and external water heads. Initially, the dam is assumed to lie flat. The internal pressure is then increased slowly until it reaches the desired value. Then the external water is applied and the equilibrium configuration is …

An analytical and experimental investigation of the response of elliptical composite cylinders
… cross-section to axial compression and internal pressure loadings is discussed. Nine eight-ply graphite-epoxy elliptical cylinders, three layups for each of three cross sectional aspect ratios, are specifically examined. The lay-ups studied are a quasi-isotropic (±45/0/90)g, an …

Bulge forming of tubular components.
… a method for shaping tubular components using an internal hydrostatic pressure combined with a compressive axial load. Initial investigations involved carrying out an extensive literature survey to determine the components which could be formed and the effects of using lubricants and different …

Experimental investigation on the dynamics of inflatable dams
… two major experimental variables are the dam's internal pressure and the stream's flow rate or the impounded water height. The existence of upstream water is shown to completely change the dynamic characteristics of the membrane-dam, now a structure-fluid system. Two aspect ratios are considered …
