采用粘塑性理论建立烧结过程的本构模型,以316L不锈钢粉末注射成形产品为例,设计出烧结过程中重力作用下弯曲梁试验和膨胀计中的自由烧结试验,分别用于标定本构模型中的粘度模量和烧结应力。通过用户子程序,在有限元求解器Abaqus^(?)上实现数值模拟,预测产品在烧结过程中的收缩和变形。考虑了重力、摩擦以及注射阶段粉末与粘结剂的偏析效应对于烧结工艺的影响,数值模拟结果与试验结果一致。

This study investigates misregistration issues between Landsat-8/Operational Land Imager and Sentinel-2A/Multi-Spectral Instrument at 30 m resolution,and between multi-temporal Sentinel-2A images at 10 m resolution using a phase-correlation approach and multiple transformation ***-registration of 45 Landsat-8 to Sentinel-2A pairs and 37 Sentinel-2A to Sentinel-2A pairs were *** correlation proved to be a robust approach that allowed us to identify hundreds and thousands of control points on images acquired more than 100 days ***,misregistration of up to 1.6 pixels at 30 m resolution between Landsat-8 and Sentinel-2A images,and 1.2 pixels and 2.8 pixels at 10 m resolution between multi-temporal Sentinel-2A images from the same and different orbits,respectively,were *** non-linear random forest regression used for constructing the mapping function showed best results in terms of root mean square error(RMSE),yielding an average RMSE error of 0.07±0.02 pixels at 30 m resolution,and 0.09±0.05 and 0.15±0.06 pixels at 10 m resolution for the same and adjacent Sentinel-2A orbits,respectively,for multiple tiles and multiple conditions.A simpler 1st order polynomial function(affine transformation)yielded RMSE of 0.08±0.02 pixels at 30 m resolution and 0.12±0.06(same Sentinel-2A orbits)and 0.20±0.09(adjacent orbits)pixels at 10 m resolution.
