【摘要】 为了进一步研究天然橡胶的力学性能,设计了非等双轴拉伸实验装置,制作了天然橡胶材料的实验试件,对天然橡胶材料试件进行了单轴拉伸、等双轴拉伸和非等双轴拉伸实验,并且对实验数据进行处理和对比。结果表明,相同材料在不同实验条件下,力学性能实测值存在差异。更多还原

【Abstract】 In order to study the mechanical character of natural rubber material, it designs a non-equal biaxial stretching experimental apparatus, makes the experimental specimens of natural rubber materials, stretches the specimens of natural rubber in uniaxial, equiaxial and non-equal biaxial drawing, compares and analyzes the experimental data. The results show that the measured values of mechanical properties of the same material in different loading paths are different.更多还原
