watermelon is handled and stored in bulk package as some other fruits and vegetables are. package height must be so appropriately selected that bottom fruit layers will receive no damage or failure. this research was performed to determine and compare the mechanical properties of two varieties in three sizes of watermelon under static load conditions to obtain parameters used in transportation ...

Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...

In this research the stress-strain curve of porous Titanium, as a common material for biomedical application, was predicted using the mechanical properties of fully solid Titanium experimental data. Modified Gurson model (Gurson-Tvergaard-Needleman (GTN) model) was used to predict the plastic response of porous Titanium in compaction. Different values of GTN parameters were used for different i...

frequency response analysis (fra) is popular technique which has been used since the last decade as a diagnostic method for transformers. however, accurate interpretation of fra measurements is still challenging. recent studies reveal that apart from winding deformation, fra data can also be influenced by moisture variation in transformer paper insulation. hence, a specific transformer’s model ...

owing to elastic and viscous characteristics embedded rubber compounds, the dissipated energy from periodic deformation is converted into heat generation and consequently, the tire may have different body temperatures for different operating conditions. in most performed investigations, just temperature distribution is considered and the mechanical behaviour of rubber parts which are highly tem...

In this work, dynamic mechanical properties of three high-manganese steels with TRIP/TWIP or fully TWIP characteristics are studied. High strain rate experiments in the range of true strain rates between ~500 and 1800 /s are conducted using a dynamic torsional testing setup. All the three steels show a positive strain rate sensitivity in the intermediate range of strain rates (up to 500 /s). Bu...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

In cardiovascular tissue engineering, mechanical stimulation of tissue-engineered constructs is known to improve tissue properties. During tissue culture, the mechanical properties of the tissue construct change. To impose a predefined deformation protocol and to avoid negative effects of excessive strain, it is desired to monitor and control deformations during load application. In a previous ...
