杆件的内力与变形计算是材料力学课程教学的主要任务之一，其确定往往涉及较大的计算量，学生在学习中易形成重计算而轻力学原理与力学思想的学习观念。将Matlab科学计算软件引入材料力学课程，将杆件内力与变形中比较繁杂的数学运算由计算机完成，一方面能使学生将大量时间用于掌握力学原理和力学思想，提高教学质量和教学效果，另一方面对培养学生用计算机解决问题与创新能力的提高有着积极的推动作用，为相关力学类课程的教学与学习提供一些参考。%Internal forces and deformation calculation of the prismatic bar is one of the main tasks of mechanics of materials,and its calculation often takes much time. Hence, many students spend much time learning the calculation but neglect the learning of the mechanical calculation principle and mechanics. However, there’re solutions of putting the Matlab scientific computing software into the material mechanics course and making more complex mathematical operations done by the computer on internal forces and deformation calculation, which enable students to focus on the principles of mechanics and mechanical thinking,which also improve teaching quality and teaching effectiveness. In addition, students are promoted to use computers actively to solve problems and to improve their innovation capability. And the solutions also provide some reference for the teaching and learning of other mechanics courses.
