This study aims to analyze the effect of profitability, corporate social responsibility and company size on value (study automotive sub-sector issuers components in 2014 - 2018). The population this were 13 companies. sample 10 was selected using purposive sampling method testing panel data regression analysis. results indicate that profitability (ROA) has a positive significant firm (PBV), Cor...
The study proposes processing animation simulation, FEM analysis, and experimental verification of multi-stage forging of stainless automotive battery fastener. The processing animation simulation can provide the realistic motions for each pass to realize how to work for the front punch and die. Stainless automotive battery fastener requires high dimension precision and narrow tolerance. In ord...
The Yoshida nonlinear isotropic/kinematic hardening material model is often selected in forming simulations where an accurate springback prediction is required. Many successful application cases in the industrial scale automotive components using advanced high strength steels (AHSS) have been reported to give better springback predictions. Several issues have been raised recently in the use of ...
Numerical simulation of sheet metal forming processes has become indispensable in the last decades. Although complexity frictional behaviour is identified as a key factor for prediction accuracy, industry commonly considers constant friction coefficient whole tool. Furthermore, influence roughness distribution tool not yet been addressed. In this study die local an advanced model evaluated thre...
Flexible forming processes are characterized by the implementation of shape-independent tools. However, varying properties of semi-finished goods in conjunction with the lack of a forming tool technology also lead to an insufficient reproducibility of the products. In order to overcome this problem a closed-loop control system for the on-line-capable process control was worked out for laser for...
We examine demand behaviour for intertemporal dependencies, using Spanish panel data. We present evidence that there is both state dependence and correlated heterogeneity in demand behaviour. Our specific findings are that food outside the home, alcohol and tobacco are habit forming whereas clothing and small durables exhibit durability. We conclude that demand analyses using cross-section data...
