GEO2
The new GEO2 software calculates the mass inertia moment of any axially symmetrical cross-section. The dimension is input as straight lines and arcs in half-section. You can also load the geometry from a CAD DXF file, if the contour is defined as a poly-line with straight lines and arcs. A table drawing with all data can be printed or taken over to CAD as a DXF/IGES file.
GEO3
GEO3 is a new software for calculation of Hertz’s pressings between 2 touching bodies (ball, cylinder, circle geometry with variable radiuses in x and y plane, planes).
GEO3 draws diagrams of pressure tension, deformation and spring rate depending on the compression load.
SR1 – shearing stress
When tightening a bolted connection a shearing stress appears because of thread traction and screw lead. This stress partly remains in the operating state. The "Calculation of service condition Sigma red,B" has been taken over from the new VDI 2230 draft. With shearing stress and maximum tensile stress in operating state, a comparative tension Sigma red,B is calculated.
Sigma red,B = (sigma²z + 3 (ktau*taumax)²)^{0.5}
In this expression, the reduction constant k tau stands for the remaining shearing stress in operating state. VDI 2230 suggests k tau=0.5. The ideal case k tau=0 is reached at hydraulically prestressed tightening, if clamping plates are pressed together when mounting and the screw is tightened with a minor torque. If the total shearing stress remained,
k tau = 1 would apply. In SR1, the tightening tools’ database was appended by K_TAU. Therefore, the field STREU_PROZ containing the variance in per cent is tropped, because it can be calculated with alpha A.
Shearing stress calculation:
Tau max = MG/Wp
With
MG = FMmax*d2/2(P/(pi*d2)+1.155*µg)
WP = pi/16 * d0³ for elastic deformation
bis WP = pi/12 * d0³ for full plastic deformation
A bit strange about the VDI 2230 draft is that the polar surface inertia moment with WP=pi/12*d³ is used for full plastic deformation when the shearing stress is calculated with MG, as the friction moment surely results in full plastic transformation only in few cases. Therefore, SR1 calculates the higher shearing stress for elastic transformation, and the permissible flowing is considered by a minor shearing stress’s influence when calculating the (theoretical) comparative tension (factor 12/16=0.75).
Sigma red,B = (sigma²z + 3 (ktau*taumax*0.75)²)^{0.5}
Or
Sigma red,B = (sigma²z + 1.69 (ktau*taumax)²)^{0.5}
For a factor ktau=0.5 (suggestion VDI2230) follows
Sigma red,B = (sigma²z + 0.42 taumax²)^{0.5}
The shearing stress is nearly insignificant.
VDI 2230 Application example
Unfortunately there is only one application example in the new VDI draft, this corresponds to example 3 of the old standard. Only the screw’s thread length was doubled from 10 to 20 mm. SR1 calculates a minimum screwing-in depth of 12.4 mm according to Dose’s expressions. In the new draft, the up-to-now incorrect calculation of the screwing-in depth has not been replaced by the practical Dose calculation, but by annother new theory.
The amount of setting calculation (so far dependant on the clamping length!) has been replaced, now roughly corresponding to Bauer & Schaurte’s methods used by SR1. In the calculation example, the setting force is now 4 times as large as according to the old VDI2230 !
SR1 – Temperature-dependent Nut
For the screwing-in depth’s calculation at higher temperatures, the reduction of yield point and tensile stress of the nut thread has to be considered. Therefore, SR1 has been appended by a database MAT_P_RE.DBF. Similar to the screw’s yield point calculation, the yield point of the specified operating temperature is loaded from the database for the nut. Intermediate values are interpolated.
The tensile strength is diverted from the yield point, it is preconditioned that the relation of yield point and tensile strength is the same for every temperature.
Rmx = Rex * Rm20 / Re20
SR1 – amount of setting acc. VDI2230 draft 11/98
The amount of setting calculation according to the new VDI draft was taken over in SR1. Now, you can choose the calculation according to the old and the new VDI, and the screw’s Vademecum. The calculation according to Vademecum had to be corrected, as the number of discretionary hyphens had not been considered yet.
SR1 - Input clamping plates
In the latest 32-bit version, problems appeared for 2 and more clamping plates at material changes, when the file was saved and later opened. The error was corrected, moreover, the material are now also shown in the list.
SR1 – Table Drawing
As size problems occurred with long texts and large numbers, the font height was decreased and the columns were widened.
SR1 – Friction Diameter
The friction diameter is calculated according to VDI 2230 with
Dkm=(dw+dh)/2
So far, the expression Dkm = (dk+dh) / 2 with head diameter Dk has been utilized. Therefor, the tightening torque was smaller.
SR1+ Plus-Version with flange calculation
An extended version of SR1 is available now, which includes the calculation of the maximum load for a single bolt (FA, FQ, Fkreq) from the flange load. Thanks to Mr. Gerhard Friedrich Dose for his suggestions and help.
The price of SR1+ is 1470 DM, the upgrade price for SR1 to SR1+ is 280 DM.
GEO1/GEO1+ Drawing
A table drawing with geometry and result data for the calculated cross-section has been added to GEO1, our profile calculation software.
WST1 – Database
The database has been appended. Approximately 250 steels and alloys, respectively, and the following material groups have been added: Heat-resisting steel, High-temperature resisting steel/alloy, alloyed tool steel, non-magnetiziable steel, vavle steel, heat-resisting cast steel, stainless steel cast.

Minus becomes Light
Because of the negative touch of the "-" sign for the light versions, it are named with extension "light" instead of "minus" in future.
Text Printout – without header
If only one page shall be printed, you can configure this setting. The page shift is ignored then.

For text printout, font, style and size can be configured now.
For the text font used with drawings and diagrams, "bold" and "italic" attributes are supported now.
