The material points of microstretch continua undergo a uniform microdilatation and a rigid microrotation. This paper is concerned with the deformation of a bar composed by two different microstretch elastic materials. The intended applications of the solution are to bone implants and various compound cylinders. The bar is reinforced by a longitudinal rod and is subjected to extension, bending, torsion and flexure. First, the problem of bending and extension is investigated. The solution involves the solving of three plane strain problems. Then, we study the problem of torsion and flexure. The results are used to investigate the extension of a right circular cylinder reinforced by a circular rod.

微拉伸连续体的材料点经历均匀的微膨胀和刚性的微旋转。本文涉及由两种不同的微拉伸弹性材料组成的杆的变形。该解决方案的预期应用是骨植入物和各种复合圆柱体。杆由纵向杆加固，并受到拉伸，弯曲，扭转和弯曲。首先，研究弯曲和延伸的问题。解决方案包括解决三个平面应变问题。然后，我们研究扭转和弯曲问题。结果用于研究由圆杆增强的右圆柱的延伸。
