ESDU 89052 introduces a computer program@ ESDUpac A8952@ for computing the inelastic stress-strain curve@ tangent and secant moduli@ and the inelastic Poisson's ratio of a metallic material from limited commonly available materials properties. It requires values of the elastic modulus and two points in the inelastic region of the curve@ and assumes that the curve can be represented by an equation containing the modulus of elasticity and two unknowns@ a reference stress and a material characteristic. The method is valid for both tension and compression cases. The program input is explained@ warnings provided when the program limitations are infringed are set out and@ through two worked examples@ the output is illustrated. The program is provided on disc as both uncompiled Fortran and compiled in ESDUview@ a user-friendly shell that prompts on-screen for input data; both versions are accessible on PC's running DOS.
