Any product is a collection of materials that have been manipulated into various shapes to form the components and joints used within the product. In fact, up to 70% of the cost to make a product is due to its materials. Therefore, getting the materials right will have a big impact on the success of a product.

EPP foams are most commonly used in automotive applications for pedestrian protection and to meet low speed bumper regulatory requirements. In today’s automotive world the design of vehicles are predominantly driven by CAE. This makes it necessary to have validated material model for EPP foams in order to simulate and predict performance under various loading conditions. Since most of the automotive OEMs depend on local material suppliers for their global vehicle applications it is necessary to understand the variation in mechanical properties of the EPP foams and their effect on performance predictions. In this paper, EPP foams from three suppliers across global regions are characterized to study the inter-supplier variation in mechanical properties. In order to understand the effect of inter-supplier variation on vehicle performance, LSDYNA rate dependent material model is developed and validated for low speed and pedestrian protection load cases.

Over the decades, several attempts have been made to develop new fatigue analysis methods for welded joints since most of the incidents in automotive structures are joints related. Therefore, a reliable and effective fatigue damage parameter is needed to properly predict the failure location and fatigue life of these welded structures to reduce the hardware testing, time, and the associated cost. The nodal force-based structural stress approach is becoming widely used in fatigue life assessment of welded structures. In this paper, a new nodal force-based structural stress recovery procedure is proposed that uses the least squares method to linearly smooth the stresses in elements along the weld line. Weight function is introduced to give flexibility in choosing different weighting schemes between elements. Two typical weighting schemes are discussed and compared.

Vehicle Hood being the face of a passenger car poses a challenge to meet the regulatory and aesthetic requirements. However, the urge to make a saleable product makes aesthetics a primary condition. This eventually makes the role of structure optimization much more important. A recent development in the Indian automotive industry, which is known for dynamics of cost competitive cars, has posed the challenge to make passenger cars meeting the regulation and having optimized cost. This work is application of structure optimization of Hood and design of peripheral parts for meeting pedestrian protection performance keeping the focus on having cost-effective solution. This paper discusses Headform compliance of the work done on one of the flagship model of Maruti Suzuki India Ltd., providing detailed analysis of the procedure followed from introduction stage of regulatory requirement in the project to final validation of the engineering intent.

An engine cooling system in an automotive vehicle comprises of heat exchangers such as a radiator, charge air cooler, and oil coolers along with engine cooling fans. Typical automotive engine-cooling fan assembly includes an electric motor mounted on to a shroud that encloses radiator core. Typically a fan shroud is made of plastic material and holds one or two motors and is supported at four corners. One of the main drivers of a fan shroud design is Noise, Vibration, and Harshness requirements, without compromising the main function - airflow requirement for cooling. Usually, stiffness requirement is not given adequate attention in arriving at optimal design of a fan shroud. Research Council for Automotive Repairs (RCAR), based in Europe, issues vehicle ratings on the basis of its performance in Low Speed Damageability (LSD) tests. One such test is a 15kph, 40% offset rigid wall impact to the front of the vehicle.

The application of induction hardening treatment plays a vital role for enhancing fatigue life of various automotive components. This will incorporate compressive residual stresses in the component at significant extent. In this paper, wide range of experiments have been carried out on Rotating Bending Fatigue (RBF) specimens made from 38MnVS6 micro alloyed steel with induction hardening up to three different case depths. The set of specimens are fatigue tested at fully reverse loading condition using rotating bending fatigue testing machine. Based on this study a surface treatment factor is evaluated. This surface treatment factor is used as an input for evaluating precise fatigue life of the specimen using FEA packages. The fatigue life evaluated using FEA is showing good agreement with the results obtained through tests on the actual specimens.

Advanced high strength steels (AHSS) have been extensively used in the automotive industry for vehicle weight reduction. Although AHSS show better parental metal fatigue performance, the influence of material strength on spot weld fatigue is insignificant. To overcome this drawback, structural adhesive was used along with spot weld to form weld-bond joints, which greatly improved spot weld fatigue performance and joint stiffness of the downgaged AHSS structures. In this study, the formulation of cohesive element based on Cohesive Zone Model (CZM) was employed to predict the onset and propagation of failure in the adhesively bonded joints in lap-shear and coach-peel specimens under quasi-static loadings. The predicted responses were compared with experimental results with good agreement.

Fatigue behavior of two types of automotive steel, quenched and tempered SUJ2 and carburized SCM820PRH, which are applied as powertrain parts are studied. These two types of steel are different in their hardness distribution from surface to core. The hardness of quenched and tempered SUJ2 is homogeneous, in contrast to that of carburized SCM820PRH (SCM) which decreases from surface to core. These steels are investigated in terms of their monotonic tensile properties and fatigue behavior. A number of predictive methods were used to describe the fatigue behavior of these steels. A simple predictive method is based on approximation of S-N curve from ultimate tensile strength. The well known Murakami’s defect area method was also applied for the prediction of the high cycle fatigue strength.

While Advanced High Strength Steels (AHSS) and next generation steel grades offer improved crash safety and reduced weight for vehicles, the global stiffness and NVH performance are often compromised due to reduced material thickness. This paper discusses an advanced method of evaluating the joint effectiveness on contribution to global stiffness and NVH performance of vehicles. A stiffness contribution ratio is proposed initiatively in this research, which evaluates the current contribution of the joints to the global stiffness and NVH performance of vehicles. Another parameter, joint effectiveness factor, has been used by Ford Motor Company to study the potential of each joint on enhancing the global stiffness. The critical joints to enhance the vehicle stiffness and NVH performance can be identified based on above two parameters, and design changes be made to those critical joints to improve the vehicle performance.
