High speed digital computer systems are used by engineers at Aptech Engineering Services, Inc. (APTECH), as an extension of their capabilities in the performance of structural analysis. By always seeking up-to-date programs for problem application, coupled with in-house development of new and efficient methods, we continually expand our capabilities. APTECH’s library of available computer programs provides considerable flexibility in handling structural problems involving:

• Arbitrary Geometries
• Pressure, Mechanical, Seismic, and Thermal Loads
• Non-axisymmetric Loads
• Orthotropic Properties
• Crack Initiation, Propagation, and Life Predictions
• Estimation of Thermal Upset or Weld Residual and
  Restraint Stresses
• Large Deflection Elastic-Plastic Solutions
• Dynamic Analysis of Large Multi-Degree-of-Freedom Systems
• Two- and Three-Dimensional Transient and Steady- State Transfer Solutions
• Transient and Steady-State Creep Solutions
• Dynamic Impact Problems
