scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. one of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. this postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (pal) and peroxidase (pod) enzymes activity in stem bending of two gerbe...

Four-roll bending process is usually used for manufacturing of seamed thick-walled and thin-walled cylinders. Due to complexity of this process, the analytical solution of plate bending in this process has not been developed completely. The existence of friction and multi-step processing makes it more difficult. Investigation of four-roll bending process using analytical and numerical methods i...

Determining a feasible bending sequence, i.e., ensuring absence of wire self-collisions and wire-machine collisions, or even an optimal minimising time energy required to perform it, is difficult time-consuming task for complex workpieces, expert operators. Introducting algorithms the computation wire-bending sequences thus crucial increase productivity production flexibility, decrease costs. T...

Accurate examination of electricity generation stemming from higher-order deformation (flexoelectricity) in 2D layered materials is a highly challenging task to be investigated with either conventional computational or experimental tools. To address this challenge herein an innovative and computationally efficient approach on the basis density functional theory (DFT) machine-learning interatomi...

Predicting the springback angle has become major production problem among tube benders. Springback is where on a mandrel-less rotary draw bending tends to bounce back after being bent when clamps are released. Accurately predicting crucial for effective bending. Machine learning (ML), popular prediction approach, was applied functions such as or function approximation, pattern classification, c...

Roll-bending technology has a high degree of flexibility and does not require special molds. However, based on the existing plastic mechanics theory finite element simulation, it is difficult to accurately analyze complex spatial relationship profile roll forming. Therefore, fixed-curvature prediction model constructed XGBoost (extreme gradient boosting), coupling effect process parameters mate...
