A General Solution for Implicit Time Stepping Scheme in Rate-dependant Plasticity %K rate %K dependant Plasticity %K Time Stepping Schemes %K Implicit %K Thick Walled Cylinder %R %X In this paper the derivation of the second differentiation of a general yield surface implicit time stepping method along with its consistent elastic-plastic modulus is studied. Moreover, the explicit, trapezoidal implicit and fully implicit time stepping schemes are compared in rate-dependant plasticity. It is shown that implementing fully implicit time stepping scheme in rate-dependant plasticity predicts experimental results more accurate than the other schemes. %U https://www.ije.ir/article_72134_2d1a8438dac1cf42994abb038d20785a.pdf
