This STP describes the development of a computer program for generating normalized stress-strain curves from raw data and development of a computer program for generating external pressure chart from normalized stress-strain curves. Part 1 of this research program is to develop a software program for plotting stress-strain diagrams for a given material from data furnished by users. The stress-strain diagram is then normalized based on the yield stress and modulus of elasticity published in the ASME Boiler and Pressure Vessel Code, Section II, Part D. The stress-strain curve is then used to develop an external pressure curve. The software program for this project is Excel Visual Basic for Applications. The input sheet permits the user to enter furnished stress-strain data as well as published modulus of elasticity and yield stress. The program then generates a normalized stress-strain curve. Part 2 of this research program was to develop a software program for plotting External Pressure Charts (EPC) from normalized stress-strain curves obtained from Part 1 for ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 applications. The External Pressure Charts are based on the yield stress and modulus of elasticity published in the ASME Boiler and Pressure Vessel Code, Section II, Part D. The software program for this part of the project is Excel Visual Basic for Applications. The input sheet permits the user to enter furnished stress-strain data as well as published modulus of elasticity and yield stress. The program then generates an External Pressure Chart.<\/p>\n
