New fractional variable-order creep model with short memory

作者：

Highlights：

• The short memory approach was adopted to split the whole creep process into three memory stages.

• A new fractional variable-order creep model was established.

• The change of fractional order is proposed to describe the variation in material properties in the loading process.
