Abstract We present LIFFE (Lithospheric Flexure with Finite Elements), a platform designed to perform lithospheric flexure. LIFFE is an easy-to-use, flexible and open-source code intended to model the flexure of a laterally heterogeneous lithosphere affected by a complex load system. This platform can be used to further understand geodynamic and surface processes such as mountain building, volcanism, and sedimentary basin formation. LIFFE is a Matlab® set of codes that allows the possibility of considering elastic thickness (Te) variations, previous deformation (variations on the plate shape), complex load systems (applied to any surface of the plate), temperature effects and decoupled infill loads. In-plane (xz) and principle stresses, gravity anomalies and models are plotted as standard outputs for a profound interpretation of the flexure. These characteristics make LIFFE a powerful tool for better describing the behavior of the elastic outer shell of Earth under loads.

LIFFE：具有有限元的岩石圈弯曲

摘要 我们提出了 LIFFE（有限元岩石圈挠曲），这是一个设计用于执行岩石圈挠曲的平台。LIFFE 是一种易于使用、灵活且开源的代码，旨在模拟受复杂载荷系统影响的横向异质岩石圈的弯曲。该平台可用于进一步了解山脉形成、火山作用和沉积盆地形成等地球动力学和地表过程。LIFFE 是一组 Matlab® 代码，允许考虑弹性厚度 (Te) 变化、先前变形（板形状的变化）、复杂载荷系统（应用于板的任何表面）、温度效应和解耦填充载荷. 平面内 (xz) 和主应力、重力异常和模型被绘制为标准输出，以深入解释弯曲。
