以下是 axial deformation 的英文范文：
"The axial deformation of a material is the change in its length along its axis, typically caused by stress." (材料在轴向的形变是指在沿着其轴向长度上的变化，通常是由应力引起的。)
希望以上内容能对你有所帮助。
Axial deformation是指轴向变形，通常发生在沿着物体或物体的某一轴向的变形。在工程、物理、地质学等领域中，轴向变形是一个重要的概念，特别是在材料科学和机械工程中。以下是一篇英文范文，其中涉及到轴向变形的概念：
"Axial deformation is a common phenomenon in many engineering applications, particularly in the field of mechanical engineering. When a material or object undergoes axial loading, it experiences a deformation along its longitudinal axis. This deformation can be either tensile or compressive depending on the direction of the load. In some cases, axial deformation can have significant effects on the performance and stability of mechanical systems, and therefore it is important to understand and control this phenomenon."
