【摘要】 以实验结果为基础,从红外热像原理出发,探讨了固体材料弹性阶段的红外辐射特征及其热力学影响因素.对弹性固体材料红外辐射场进行的模拟计算和对比分析表明,实验结果与理论计算一致,说明红外辐射升温区和降温区对应于固体应变场的压应力区和拉应力区,从而初步揭示了固体材料载荷初期红外辐射特征的热力学影响因素和来源.更多还原

【Abstract】 From point of the experiment view,based on the infrared radiation imaging foundation,the infrared radiation characteristic and thermodynamics effect of elastic deformation for solid are discussed.Comparing and discussing of infrared radiation field and strain field shows the zones of increasing and decreasing of temperature are corresponding to compressing and expanding respectively.This explains the main effect of elastic deformation on infrared radiation.更多还原
