software tool for mathematical modelling

hi, i am a post graduate student from india and im undertaking a project related to piping. my title is limit load analysis of pipe bends with ovality(a mathematical approach). is there is any software tool available for generating mathematical equatiions for calculating required wall thickness in pipe bends with ovality as per asme standards. i am going to consider it as a nonlinear analysis at the bend section ... and if you need further info to help me pls do inform me.. i am just a beginner so pls help me industrail giant seniors
