  Elasticity is one of the most fundamental mechanical properties of solid. In
high-throughput design of advanced materials, there is an imperative demand for
the capability to quickly calculate and screen a massive pool of candidate
structures. A fully automatized pipeline with minimal human intervention is the
key to provide high efficiency to achieve the goal. Here, we introduce a
tool-kit MyElas that aims to address this problem by forging all
pre-processing, elastic constant and other related property calculations, and
post-processing into an integrated framework that automatically performs the
assigned tasks to drive data flowing through parallelized pipelines from input
to output. The core of MyElas is to calculate the second and third order
elastic constants of a solid with the energy-strain method from
first-principles. MyElas can auto-analyze the elastic constants, to derive
other related physical quantities. Furthermore, the tool-kit also integrates a
visualization function, which can, for example, plot the spatial anisotropy of
elastic modulus and sound velocity of monocrystalline. The validity and
efficiency of the toolkit are tested and bench-marked on several typical
systems.
