Abstract: Conventional approaches of physical experiments for the effects of cure kinetics in composites materials may lack in capturing lower length scale effects at bulk level. The computational state of the art approaches has not focused on the issue of scale bridging between multiple length scales for manufacturing effects in composites. This limits its usability for specific materials or situations. Embodiments of the present disclosure provide systems and methods that implement a multiscale analysis for determining residual stress and deformation profiles in molded parts comprising composite material. More specifically, present disclosure implements the multiscale analysis wherein a thermal chemical analysis and thermal mechanical analysis are linked to achieve two-way coupling for curing effects at each node/point of molded parts having composite material to provide flexibility and versatility in terms of exploring multiple material combinations without major modification in the approach.

Abstract: An integral reinforcement design method of an external frame-brace based on a random capability spectrum is provided, and the reinforcement design method includes: evaluating an original structure before reinforcement by using a random capability spectrum method; performing a reinforcement analysis on an external frame-brace sub structure by using the random capability spectrum method to obtain a reinforced structure; and performing a reinforcement verification on the reinforced structure by using the random capability spectrum method. A performance based integral reinforcement design of the external frame-brace sub structure is achieved through considering uncertain factors, as well as capability spectrums and demand spectrums before and after the reinforcement, and converting the integral structure to equivalent single degree of freedom to obtain performance points.

Abstract: Method for predicting a stability of a steel cylinder including: in response to the steel cylinder tilting toward a seaward side at an arbitrary rotation point, obtaining a safety factor for the steel cylinder tilting toward the seaward side by determining an anti-tilt moment and a tilt moment when the steel cylinder is tilted to the seaward side; under a same rotation point, in response to determining that the steel cylinder is rotated toward a land side, determining the safety factor for the steel cylinder tilting toward the land side; taking a smaller safety factor as the safety factor under the rotation point; re-selecting a new rotation point, determining a safety factor corresponding to the new rotation point, and taking a safety factor with a smallest value among all rotation points as a final safety factor; and generating, based on the final safety factor, an anti-tilt instruction.

Abstract: A reinforced shipping container along with method for generating the reinforced shipping container are described herein. A digital model of the shipping container is received and simulated with an expected load. The expected load may represent an expected loading scenario for the shipping container during shipment. A reinforcement profile is determined based on stress data developed from the simulation to increase a strength-to-weight ratio of the shipping container. The reinforcement profile is used to apply a reinforcing agent to a substrate used to form the shipping container in a selective manner to reinforce regions of the shipping container that will experience stresses during shipping.

In view of the existing problem of difficult calculation of quantitative analysis on the bearing performance of a dynamic driven pile of a mudstone foundation and the damage characteristics of mudstone around the pile, a damage constitutive model of mudstone with a damage variable D determined based on a stress state and associated with a rock failure criterion is established; model parameters are determined based on results of a triaxial test; a relationship between a critical damage variable and a confining pressure is established; and the damage characteristics of the mudstone around the dynamic driven pile are analyzed, whereby pile tip resistance is calculated. The requirements of quantitative analysis on the damage characteristics of a pile tip are met.

Abstract: The invention belongs to the technical field of quality control of steel plates and strips products, and relates to a prediction method of crown of steel plates and strips based on data driving and mechanism model fusion. By establishing an outlet crown mechanism model of a hot continuous rolling, the mechanism model and a DNN model are combined to establish a DNN model for predicting crown of steel plates and strips, and the calculated value of the mechanism model is taken as a benchmark value of the outlet crown. The deviation amount between the benchmark value and the actual values of the outlet crown is taken as output of the DNN model for predicting crown of the steel plates and strips, and then sum of the predicted value and the benchmark value based on the DNN model for predicting the crown of the steel plates is taken as the final predicted value of the crown of the steel plates and strips.
