Updated 11 June 2000


BOLTCALC will determine whether or not a bolted joint will sustain the forces acting upon it. If the joint is being designed it can estimate the size of bolt required for the application. Once the bolt size has been estimated, or details of an existing joint have been entered, detailed calculations can be performed. The calculations will determine whether or not the bolt will fail by the joint not being clamped together sufficiently, direct overload of the bolt, or by fatigue failure.

A demo version is available. Requires Windows 9x or NT.

Energy Conversion 1.1 calculates thermodynamic and transport properties of gaseous, liquid, and solid species (TP, HP and SP) in U.S. customary and International units. It also contains coefficients for the calculation of physical properties. The user has the ability to use the coefficients to carry out independent engineering calculations involving physical properties of various species. Steam approximations for both saturated and superheated areas, the analysis of power cycles (Carnot, Brayton, Rankine, Otto, Diesel, Magnetohydrodynamics, and Fuel Cell), power cycle components and processes (compression, combustion, expansion, heat transfer, and mixing), and compressible flow (velocity of sound, Mach number, stagnation and static properties, nozzle, normal shock, diffuser, and thrust).

A Demo is available which requires Windows 3.x '9x or NT.

The Laminator - Classical Analysis of Composite Laminates

The Laminator is a Windows 95/98/NT shareware engineering program that analyzes laminated composite plates according to classical laminated plate theory. Input consists of ply material properties, material strengths, ply fiber orientation and stacking sequence, mechanical loads and/or strains, and temperature and moisture loads. Output consists of apparent laminate material properties, ply stiffness and compliance matrices, laminate "ABD" matrices, laminate loads and mid-plane strains, ply stresses and strains in global and material axes, and load factors for ply failure based on Tsai-Hill, Hoffman, and Tsai-Wu failure theories.

The Laminator is a fully functional "Shareware" program. Online registration available ($20).

OmniCon 98 is a unit conversion program designed to meet the high expectations of professional engineers and scientists. However, OmniCon's easy-to-use interface means that everyone can easily perform conversions without any instruction. OmniCon 98 ships with over 500 units in 43 physical quantities - it is therefore possible to perform thousands of unique conversions! If you find that a conversion you need is not provided in OmniCon 98,you are free to add your own custom units and custom physical quantities. OmniCon 98 is intelligent and only displays the maximum allowable number of significant figures available for a particular conversion. This function separates OmniCon 98 from all other unit conversion applications. OmniCon 98 uses American and Canadian Government standards as the source of its conversion factors for the utmost accuracy.

Please note OmniCon 98 is a "Shareware" program, this version is limited to running 45 times before registration.

TORQUE is a program which is designed to assist the Engineer in the solution of problems related to the torque tightening of threaded fasteners. The program determines both tensile stress due to the elongation of the fastener, and the torsional stress due to the applied torque. It accounts for the frictional effects in the thread and between the nut face and clamped surface. Account can also be made for the effects of a reduced shank diameter and a prevailing torque.

A demo version is available. Requires Windows 9x or NT.
