comprehensive detailed engineering analysis and design

procedure named ALVA-30-5.2/IBMF, that can be used in the

case of cylindrical shells loaded with high pressure,

temperature and external or internal mechanical loading, and in

reference to the design options as shown in this site page

services4.html

The work is applicable for the industrial structures and items, and since this work is a

result of a fluent mathematical procedure it has nothing to do with any design code. A

design code specifies only that a certain problem can also be solved by detailed analysis.

Evidently in performing a detailed analysis we are not using any code information,

eventually we can show that our procedure ends up with the same result or equation

mentioned in a design code which doesn't mean, if it is necessary to mention, that the

detailed analysis procedure is done in accordance with a design code.

Except the information obtained from the experimental stress analysis, a reference

design code is a consequence of the detailed engineering analysis procedures.

Computer Program Description regarding the above work, now completely attached here

in the Web site pages "services" Page 1,2,3, "services2" Page 4,5,6 and "services3"

Page 7,8 contain comments and a reach engineering analysis procedure description. At

these, a few additional program output pages are also attached to this site. The basic

analysis procedure that we have to follow, namely: Sustained and Thermal Loading

Analysis, Combination of the Sustained and Thermal Loading to satisfy certain

requirements for the five possible fatigue equations, and ending with the Fatigue Analysis

are fully discussed and mathematically developed in the program project version (P).

The purpose of the attached site work is mainly to show the engineering level which a

work can be commented and done at, and also to mention that it is ready to be involved in

the new or old projects engineering problems. The shell-lug itself interface item, the

attachment in our work, cannot be, from the engineering analysis point of view, any

geometrical configuration we can think of. There are also analysis procedures for the

rectangular and square attachments. It is clear that the weld, the attachment and the lug

itself is a block not examined by the present program. I would say that this work is

addressed to those interested to know more about cylindrical shell engineering analysis

procedure.

ALVA-30-5.2 computer program is a powerful detailed engineering analysis and design

procedure for cylindrical shells having the mechanical loading conditions as shown in

the Design Options 1 to 4 (Web site page "services4"), and a parabolic temperature

gradient condition. Information about the stress distribution within the analyzed shell

characteristic points, due to the loading conditions, are given in detail (Web site page

"services7") and therefor a rapid answer for a modified input can be obtained if the fatigue

condition is not satisfied or for any other reason you could consider.

Under normal and convenient circumstances, ALVA Engineering can take subjects from

the attached Professional Profile to be commented or developed as a detailed

engineering procedure.

Comprehensive Engineering Analysis

Comprehensive Engineering Analysis

Piping with integral round attachments on vertical tangents, and constructed to fulfill

specific requirements, such as those specified by the ASME Section III Subsection NB

Code, needs the typical engineering procedure and results provided by the ALVA-30

design OPTION 2 computer program, to assure the engineering compatibility

design-nuclear power plant structures design requirements. The program can be applied

immediately after the load at the pipe lug-attachment level is known from the piping

flexibility analysis, and the certainty that the General Primary Membrane Stress in the shell

(pipe) zone where the strain due to the lug load is active, does not exceed the prescribed

allowable stress intensity value. The program takes the pipe lug zone analysis from the

beginning, and the situation is such that the piping examined by the ASME Section III

Subsection NB simplified analysis (equations 9, 10, etc.) procedure, can be rejected.

Since some input data for this program design OPTION 2 piping version are taken from

the piping flexibility analysis results, and with a few exceptions the input data are

common, the present program's engineering procedure concept can be embedded into

piping flexibility analysis program. See the Web site pages "services9, 10 and 11" for

details.

Experimental stress analysis, and a simplified analysis is very much a consequence of

the detailed analysis with some shortcuts and assumptions, probable given a bulk

stress, therefor a stress without being in three orthogonal planes, as is required to

perform a detailed analysis. The time for the simplified analysis is gone.
